This article from the Economist (2014) suggests that class mobility hasn't changed very much in the past 40 years, but given the widening gap between the rich and the poor, "the consequences of an accident of birth have become bigger." And there's also the concern that "living standards for the non-elite will stagnate for a long time." Also, there's this video from the Brookings Institute. I haven't watch it yet, but it looks topical.
