For decades, an increasingly loud chorus has claimed that economic inequality is primarily driven by class, with other possible reasons for disparities, such as race, playing a lesser role. They say that it is counterproductive to focus on inequality between races—instead, it is better to consider the inequality between all of America’s poor and its increasingly rich elite. A new study (pdf) by economists at Stanford, Harvard, and the US Census Bureau seems to refute that idea.

The paper, which assesses data on intergenerational economic mobility for 20 million US children and their parents, shows that when it comes to racial inequality, primarily between black and white Americans, class can’t explain the gap.
