Monday night’s town hall came as a landmark new study shows that rich white boys are likely to remain rich as adults, but that rich black boys are more likely to become poor or middle-class as adults. The study, led by researchers at Stanford, Harvard and the Census Bureau, debunks widely held ideas about income inequality and race. It shows how racism still deeply affects African-American men’s lives, even if they grow up in the country’s richest neighborhoods and have high levels of education. The study also reveals the disproportionate impact of the criminal justice system, showing how black men who were raised by millionaires are just as likely to be incarcerated as white men who were raised in poor households.
