Some years ago PBS funded a four year documentary of kids in Berkeley. (Home of diversity and multiculturism). Now this is far away from the neglected little toddler, but they show highlighted that the kids seemed to interact by race even though the barriers were supposedly gone. The blacks thought the school was failing them and their only chance was in sports. The hispanics held the school student body council, but the project had to be dropped because none of the hispanic kids stayed in school for the senior year.
Your point about Hispanic kids during their later years is well taken. Hispanics around these parts have a rep for dropping out of school early. Everyone has decided that they are working, legally or not.
