Studies show that social inequality affects the health of populations more than any other factor – more than diet, smoking, exercise and even more than access to medical care.2
Americans suffer the worst health in the industrialized world because they live in the most unequal society in the industrialized world.
Inequality is built into and generated by the capitalist system. Capital is created when employers pay workers less than the value of the goods and services they produce. The resulting profit, or capital, is used to extract more capital. As this process repeats over time, capital accumulates at the top of society and misery accumulates at the bottom.
The strategy of divide-and-rule generates even more inequality: between men and women, White and Black, national and foreign-born, straight and gay, etc.
As social inequality grows, the health of the entire population suffers, not just those on the bottom.3
How does inequality do so much damage?
Power = Health.
A 2008 study found widening differences in health between income levels in America. (Income level is often used to measure social status.) The nation’s poorest adults were nearly five times more likely to be in “poor or fair” health than the richest, and at every income level the wealthier group was healthier than the next lower one. This trend was seen in all racial groups.10 Michael Marmot, who studies the link between social status and health, explains,
“Your position in the hierarchy very much relates to how much control you have over your life…Sustained, chronic and long-term stress is linked to low control over life circumstances.” 11
Under capitalism, only a few people get to make the important decisions. The rest of us get no say over how work will be organized and how social resources will be used. We don’t get to decide if we will build more schools or more prisons, wage war or make peace...
Human beings cannot be healthy in class-divided societies. From birth to death, capitalism ranks people on a vertical scale, with those higher up being treated as more worthy than those lower down. The unequal relationship between bosses and workers is maintained by divide-and-rule policies that generate more inequalities based on gender, skin color, sexual orientation, religion, nationality, etc. These divisions rupture social bonds and generate sickness throughout the population.
Universal access to medical care would reduce some of this inequality. However, even the best medical system cannot eliminate the health-damaging effects of poverty, social discrimination, unsafe work, bad housing, poor schools and being denied the right to make decisions that affect our lives. To end these miseries, we must eliminate class divisions and all the other inequalities that follow.
Human sickness is a product of sick social relationships, and human health is a product of healthy social relationships. Replacing class divisions with a cooperative, socialist society would reduce the burden of disease and raise the level of health more than any other measure.
