A series published in The Lancet recently investigated the effect of income inequality on the health of Americans. While incomes for those in the top have grown, extreme poverty has also grown in the US. In fact, more than 1.6 million households in the US survive on less than $2 per day; a number double that of the 1990s. The cycle is not likely to be broken either, barring major social change. Differences in aspects ranging from zoning laws, access and quality of education, and inheritance laws continue these inequalities through generations, making it more difficult to rise out of poverty.
