As stated in the nytimes.com, "The Richest American Men Live 15 Years Longer than the Poorest 1 Percent," which is an absolutely staggering statistic, and is proof positive, that those that have a lot of money, besides having all the advantages that money brings to the table in the sense of influence, material goods, and pleasure, are also considerably healthier than those that have little or nothing, who besides lacking in influence, material goods, and probably pleasure, die a heck of a lot earlier than their very rich counterparts, though both the rich and the poor, are citizens of the very same republic.
In a country in which the quality of one's housing, food, entertainment and material goods, is correlated highly with their income, credit worthiness, and material assets of that given individual or household, it is also clear that money buys better health insurance, better healthcare, and better access to medical facilities and because physical bodies are going to need periodic checkups as well as care, those that have good insurance and can afford to pay for good medical treatments as well as necessary medicines, are going to be a lot better off than those that can't afford to do so, or struggle to do so, and the life expectancy of those that are rich as compared to those that are poor, clearly state this.
It doesn't seem fair that those that are rich and that have all the material advantages to begin with, are also afforded all the health advantages that having money and influence also brings to them. Further, for those that are in the middle class or thereabouts, the richest Americans still live longer than those in the middle class, as the correlation between life longevity correlates closely with household income, so that, the more household income, the longer the living, whereas the bigger the gap between those incomes, the greater the disparity in length of life between those incomes.
There are probably myriad reasons why very rich people live longer, besides the fact that their access to high quality healthcare is never limited by their lack of monetary funds; of which, a couple of those salient reasons comes down to food so consumed, of which poor people and those on tight budgets are more liable to having to consume food that isn't healthy or properly nutritionally balanced for them over the long term, as well as people with limited income are more prone to living in areas of the country in which their air quality, or their water quality, or their soil quality, or their housing or neighborhood quality, have suspect aspects to them, that over a period of time, are damaging to their health.
While it is true that the rich cannot take their material assets with them, and that eventually, after an extended period of time, that they will meet their Maker, the fact that just being wealthy, means longer life, signifies that healthcare in America is treated more like just another commodity, that rich people can buy more of and of better quality of; whereas for the indigent, they get the lackluster leftovers, and in our mainly for-profit healthcare world, that means, that they get virtually nothing, and are left to die, before their time, for their lack of the means to pay or to have provided for them, good healthcare.
