Poverty is Poison by Paul Krugman
NY Times; February 18, 2008
"...neuroscientists have found that many children growing up in very poor families with low social status experience unhealthy levels of stress hormones, which impair their neural development. The effect is to impair language development and memory — and hence the ability to escape poverty — for the rest of the child’s life."
