Previously I wrote about educational composition within under-35 wealth quintiles as a way of testing the reliability of a prison study which used wealth at 20-28 as a marker for class. (Again, I must note that I had much help from Matt Bruenig, both for the idea and the execution.) My main result was that the bottom wealth quintile for 1989 (near when their study was done) was unusually well-educated, thus demonstrating that wealth at a young age is not a reliable marker for class.
