Is inequality shortening your life span?

health / poverty chartWhite, Black, or brown, we’d all live longer in a more equal, less status-driven society.

Part 11 of an 11-part series on race in America.  This piece has been divided into  two parts. The second half will run next week

Imagine you got to choose whether to be born Black or born white in America. Here are a few health statistics that might inform your decision:

If you chose to be born white, your chances of dying of Parkinson’s disease would be twice as likely as if you chose to be Black. Your chances of dying from cirrhosis of the liver or Alzheimer’s disease would be 25 percent higher. As a white person, you’d also be two and a half times more likely to commit suicide.

Based on those facts alone, the decision to be born white might sound like a pretty bad idea. And sure enough, life doesn’t work out well for many millions of white people in America. But you might also consider everyone has to die of something, and dying from these particular causes has some advantages.

As terrible as Alzheimer’s and Parkinson’s are, for example, almost no one dies of them unless they’ve previously managed to escape death from other causes for 75 years or more. Cirrhosis of the liver tends to kill at younger ages, but you can still spend many decades of hard drinking before it catches up with you. Even for the chance to commit suicide, one typically has to have survived at least until one’s teens, and suicide is more common among those who have succeeded in growing old than it is among those who are still young.

By contrast, consider the pros and cons of choosing to be born Black, based on life tables alone. To be sure, opting to be Black would reduce your chances of dying from diseases caused by risk factors that rise with age. But it would also severely reduce your chances of living to even your first birthday, let alone growing old enough to retire. This would be particularly true if you chose to be Black and male.

To start with, your chances of dying before your first birthday would be roughly 2.3 times greater than if you were born white. If you managed to make it to age one as a Black male child, your chances of dying before your 5th birthday would be 80 percent greater. If you survived to age 15, you’d have a 60 percent greater chance of dying within the next 10 years. If despite these elevated risks of premature death you nonetheless managed to get to your 45th birthday, you’d still be 80 percent less likely to live long enough to collect Social Security than if you had chosen to be white.

If you were Black, you would also, of course, substantially elevate your chances of growing up in a poor, crime-ridden neighborhood, and the health consequences of living in that kind of environment are extremely adverse. If your neighborhood were, say, New York’s Harlem during the 1990s, as a young man you’d have only a 37 percent chance of living to see 65. By contrast, according to a seminal study published in the New England Journal of Medicine, if you’d chosen to be white and wound up living in the unremarkable, predominantly white middle-class Detroit suburb of Sterling Heights, your chances of still being alive at 65 would be above 89 percent.

So what would you choose? It may be longevity is not the only measure of the good life. You might also, with enough luck and fortitude, be able to overcome the highly elevated health risks of choosing to be born Black. Indeed, it is a curious fact that among African American males who live to an advanced old age (85 years or older), the chances of living for another year are actually greater than for white males of the same age — presumably because the few African American men who have survived that long have remarkable constitutions.

Yet who would ever choose to face this pattern of competing health risks across their life course? It’s far more important to have a good chance to become elderly in the first place than to embrace the tiny chance of becoming a centenarian in the unlikely event you’re not already dead by 65.

The vast disparities in health and longevity that exist between the races in the United States violate a fundamental idea of justice we all carry with us at least to some degree. It is the idea of justice as fairness, of what kind of world we would choose to live in if, as the philosopher John Rawls framed it, we were all impartially situated as equals before being born and did not know what our station in this life would be. A society that resists ending the preventable causes of these racial disparities in heath is a society resisting justice.

Imagine if, before you were born, you were told you could choose to be born either Black or white in America. But if you chose to be white you would live in poverty and if you chose to be Black you would be in the lower-middle class. In this thought experiment, you wouldn’t know anything about what our world is actually like except for estimates of life expectancy for different categories of people.

Those estimates would tell you that choosing to be white would bring you very little, if any, advantage to health if you were also poor. For example, according to data developed by the Robert Wood Johnson Foundation, approximately 35 percent of whites living below the poverty line report themselves to be in only poor or fair health. This is quite close, after we adjust for age differences, to the 32 percent of poor Blacks who report fair or poor health.

Meanwhile, the health status of both Blacks and whites improves dramatically with higher income while the gap between them remains small. Among Blacks and whites living at just four times the poverty rate, for example, the percent who report poor or fair health drops to 8 percent and 6 percent respectively. Your race per se, in other words, plays little role in predicting your health compared to your income.

What explains the residual difference in the health status of Blacks and whites who have the same-size pay check? Researchers suggest it may reflect in part the reality that at any given income level, Blacks tend to have fewer assets than whites, such as home equity and financial savings. A Black family earning, for example, $50,000 in income is less likely to own its own home, less likely to have received an inheritance, and more likely to be encumbered by debt than is a white family with the same income. Middle-class Black families are also more likely than middle-class white families to bear the health consequences of having lived in poverty in the past.

The gap in health status may also reflect the fact that among families with similar levels of income, as well as educational attainment, Blacks are more likely than whites to live in neighborhoods with higher concentrations of crime, poverty, pollution, liquor stores, “junk food” outlets, and inferior health care. Conscious or unconscious bias among health care providers may also be at work in explaining the racial health gap, though your chances of receiving substandard health care in the United States vary far more according to where you live than according to the color of your skin.

Yet even if they remain remarkably small at any given level of income, racial disparities in health do exist. And these disparities are large enough to make it rational (if health and life expectancy are the only criteria) to prefer being born a poor white American than a poor Black one. But the differences are also far too small to make it rational to prefer being born a poor white to being born a rich, or even lower-middle-class, Black. Again, the health status of Blacks who live at just above the poverty line is substantially better than that of whites who live below it.

There is a reason why, in English, we use the word “poor” to refer to both a lack of money and a lack of health. Both historically and still largely today, poor people are likely to have poor health, almost regardless of other circumstances.

That poverty is deadly is not hard to understand, at least at the extreme. To be very poor means not having enough to eat, being exposed to the elements, and living in areas where homicide and addiction are leading causes of death or where your access to appropriate health care is minimal or nonexistent. In addition, both historically and today, getting seriously sick is likely to make you seriously poor, even if you weren’t before.

But if our goal is to overcome the vast disparities in health that exist in the United States, especially for African Americans, we have to absorb two more difficult facts. These facts are noncontroversial among epidemiologists, even if they remain unfamiliar to most Americans.

It’s not just extreme poverty that is bad for your health; so is having less autonomy and status than others, regardless of your income. Among people who have plenty to eat, have equal access to quality health care, live in safe neighborhoods and hold down jobs, health and life expectancy declines with socioeconomic position. While it is not hard to understand why truly impoverished people of all races die younger than middle-class people, it’s also true that middle-class people die younger than upper-middle-class people, and that upper-middle-class people die younger than rich people, even though none but the very poor are wanting for the basic necessities of life.

It is that the wider the disparities in status and power that exist between people within a given workplace, city, county, state, or country, the more premature deaths happen. Crudely put, inequality kills.

It’s a pattern that’s found, in greater or lesser degree, under all forms of government, within rich countries and not-so-rich countries, in the East and in the West. It also holds true in countries with universal health care and those without, and among different U.S. states.

The first place researchers rigorously documented this pattern was in the United Kingdom. There, starting in the 1960s, a team headed by the epidemiologist Michael Marmot began a long-term study of the health of British civil servants. These bureaucrats had much in common with one another. None lived in poverty; none were rich. None had jobs that posed any clear physical danger beyond the risk of paper cuts. All had equal access to the fully “socialized” British health care system.

Yet as the study went on it became clear these bureaucrats were vastly different from one another in their health and longevity. Specifically, among employees of the same age, those who occupied the bottom of the organization chart as typists, clerks, and the like were four times more likely to die over the next 20 years as were administrators at the top of the hierarchy. Moreover, the differences in death rates did not just exist at the extremes of the organizational ladder. At every step in between, health and life expectancy were better one rung above and worse one rung below.

At first, researchers suspected this social gradient of disease must be related to lifestyle. People at the bottom of the organization tended to smoke more, for example. But it turned out if you were an administrator and smoked two packs of day, this was far less dangerous to your health than if you were a clerk who did the same. Similarly, if your blood pressure or cholesterol levels were high, or if you rarely exercised, being higher in the organizational chart made these conditions less threatening to your health than if you were lower. This was true even though people at the bottom of the organization tended to see doctors more frequently.

Since then, similar correlations between health and social rank have been observed just about everywhere researchers have looked. It turns out Hollywood actors who win the Academy Award live four years longer on average than their costars in the same movie. And they also live four years longer than actors who were nominated for the award but did not win. This four-year difference in life expectancy may not sound like a lot. But to keep the implications for population health in perspective, consider if all deaths from heart disease were magically eliminated while deaths from other causes remained the same, the improvement in life expectancy for the population as a whole would come to just four years.

One way researchers have tried to explain these and similar findings is to posit that the losers in our society have become losers because they have poor health. This is no doubt true in some cases. Clearly, if you’re in the hospital for months following a car crash, lose the ability to walk, and go through life thereafter with hideous facial scars, it is bound to negatively affect your career prospects. The same would be true if you were born already addicted to narcotics or positive for HIV.

Or to take a less extreme but far more common example, say you are a low-level employee working a dead-end cubicle job and find yourself afflicted at age 30 with prolonged bouts of depression, insomnia, and more than an occasional hangover. It is possible that these conditions will make it less likely that you will rise to the top of the ladder than if you bounced out of bed each morning feeling like the picture of health.

But to conclude in this instance that your lack of upward mobility is because of your poor health is to beg the question of why you have developed these afflictions in the first place. Maybe you would drink in any event. Maybe you’d describe life as stressful regardless. But would you drink as much, and feel so bad about it in the morning, if you also felt (like that famous, highly effective, long-lived alcoholic Winston Churchill) that you were in command and getting important stuff done?

To continue this thought experiment, what if you did not feel slighted and powerless at work; if your boss didn’t make eight times your income but only double; if he didn’t seem to look down on you and “your kind”; if losing your job didn’t mean losing what little control you have over your life? What if you didn’t feel variously envious, intimidated, and infuriated by coworkers, neighbors, and people you see on TV who seem to have it all; if you could point to some way of keeping score in this life by which you were a winner and life had meaning?

The specific biological mechanisms that lead from feelings of relative powerlessness and low status to specific diseases are not well understood at the molecular level. Some researchers have pointed to the role of cortisol, a steroid hormone released by the adrenal gland in response to stress that has the effect of suppressing the immune system. Among people who are overweight, those with high levels of cortisol are more likely to contract diabetes than those with low levels.

More than 200 laboratory studies have also shown the highest cortisol levels are found in people required to perform tasks outside their control that involve, as the epidemiologist Richard Wilkinson puts it, “threats to self esteem and social status in which others can negatively judge your performance.” A hard-charging executive may use the word “stress” to describe his reaction to the burdens of command, but it is his cowering subordinates who are most likely to feel the kind of stress that literally changes body chemistry.

The negative effects may be compounded if those subordinates must also endure the stress and humiliation of either perceived or real racial or class discrimination. And the effects may be further multiplied if they have also internalized feelings of inferiority based on these or other negative stereotypes or social constructions.

In an intriguing study at Emory University, researchers found, for example, that Black men who reported being victims of racial discrimination experienced an increased risk of heart disease. But a much greater risk of heart disease was found among African American men who agreed with negative statements about Blacks. Indeed, the highest rates of heart disease were found among African American men who said they were not personally victims of racial discrimination but still viewed their own race as inferior. Put another way, being or believing yourself to be the victim of racial discrimination is not good for your health, but what’s really bad is to absorb a social belief system that says you are at the bottom.

Suppose, before you were born, you were told you had to be a white man, but you could choose whether you would live out your days in Mississippi or Minnesota. If you could not know anything else about these states except their life tables, what would the rational choice be?

The life tables would tell you that if you wound up a white man in Mississippi, your chances of not dying before age 65 would be little better than 74 percent, and that if you did live to that age, you could expect to be dead within 15.35 years. But if you were a white man in Minnesota, your chances of living to age 65 would be better than 83 percent and your remaining life expectancy at that point would be 17.49 years.

The choice would seem clear, but what explains how stark it is? One big difference between Mississippi and Minnesota is the number of Black people in each state. But unless you think Blacks in Mississippi are responsible for the deaths of huge numbers of white males — and they aren’t — that can’t be the reason why white men in Mississippi live shorter lives than white men in Minnesota. Nor are differences in median household income between whites in Mississippi and Minnesota large enough to explain such a large disparity in health: few whites in either state are poor enough that their health is threatened by lack of food or shelter.

The key factor may be how these states differ in their degree of social and economic stratification. Mississippi is among the states with the highest inequality of income. Moreover, throughout most of the last two decades Mississippi has led the nation in the growth of income inequality, whether as measured by the difference between those at the very top and those at the very bottom or by the gap in income between the middle class and the very rich.

Minnesota, by contrast, has much lower disparities of income, and is much more egalitarian in many other dimensions as well, including educational attainment, access to health care, and even, dare we say, cultural style. Garrison Keillor’s joke about all the kids in Lake Wobegon being “above average” contains an important truth: Minnesota is not a place where invidious distinction is typical, or kindly looked upon. And perhaps because of that, it is also not a place where stress and insecurity about social standing and loss of face is very common.

Within the United States generally, disparities in health among different segments of the population have increased in lockstep with growing disparities in income and education. By now it’s to the point that poorly educated white Americans, for the first time ever, are experiencing an absolute decline in their average life span. White males with fewer than 12 years of education now have a life expectancy of just 67.5 years — just six months longer than the standard Social Security retirement age set under current law for today’s middle-aged and younger Americans. The gap in life expectancy between white females who go to college and those who don’t widened from 1.9 years in 1990 to 10.4 years in 2008.

Meanwhile, for all but those at the very top of the ladder, and perhaps even for them, life is shorter than it likely would be if we lived in a more equal, less socially competitive and status-driven society — including one that was less obsessed with status distinctions based on race, education, and profession or that paid less notice than Americans have since the 1980s to who has the biggest McMansion, the most designer clothes, or the latest, snazziest smartphone. Inequality may not be an equal-opportunity killer, but few escape its mortal consequences.
