These stats are interpreted wrong. Assuming poor college kids started out from 1st quintile(<20%), then at 40 yo, 41% of them are above 4th quintile(>60%), while only 19% for poor HS dropouts. And there are more poor college kids in 5th quintile(>80%) than poor HS dropouts, 20% to 16%. This is from conclusion of the paper: "Nonetheless, we find it encouraging that a set of well-evaluated programs appear, according to the model, to make it possible to close most of the gap in the lifetime incomes between children born into lower and higher income families"
