Over the weekend the Financial Times reported that poverty stunts neural development. 

Neuroscientists said many children growing up in very poor families with low social status experience unhealthy levels of stress hormones, which impair their neural development. That effect is on top of any damage caused by inadequate nutrition and exposure to environmental toxins.

Studies by several US universities have revealed the pervasive harm done to the brain, particularly between the ages of six months and three years, from low socio-economic status.

Add this to the growing list of reasons the U.S. should do more to fight poverty abroad and at home.
