In the now obscure book "POVERTY" by Robert Hunter, written in1965, Mr. Hunter examined poverty in the U.S. from 1930 to 1950.  During that time many cultures shared the stigma of poverty; Irish, Italian, Jewish, Oriental and African-American.  These were unskilled laborers who could barely maintain a residence.

If we fast forward to today, what has changed significantly is the demographic of those impoverished.  Poverty is primarily in the African-American culture.

A recent study by the U.S. census bureau  shows that Asians have the highest income followed by whites then Hispanics, with African American firmly at the bottom where we have been for the last 200 years.

Clearly people who work primarily at unskilled labor jobs are not given insurance.  So this group, over decades of not having insurance, would have the worst health.

Perhaps its not bad genes or ignorance of the need for health care.  Medical care is very expensive, and without insurance, people who live at the low income level just can't afford medical care.
