An article in The New York Times today highlights several recent studies suggesting that education gaps between rich and poor students are growing -- from elementary school through college. At the same time, race-based gaps are narrowing. “We have moved from a society in the 1950s and 1960s, in which race was more consequential than family income, to one today in which family income appears more determinative of educational success than race,” said Sean F. Reardon, a Stanford University sociologist.
