This has happened all over the country, of course, but California has led the way — it has 630,000 students in charter schools, more than any other state, and the Los Angeles Unified School District has more than 154,000 of them. Charters are associated with choice and innovation, important elements of the good life that California is famous for. In a deep-blue state, that good life theoretically includes diversity, and many white liberals believe charters can achieve that, too. After all, a do-it-yourself school can do anything it wants.

But that’s what makes me uneasy, the notion that public schools, which charters technically are, have a choice about how or to what degree to enforce the social contract. There are many charter success stories, I know, and many make a diverse student body part of their mission. But charters as a group are ill suited to the task of justice because they are a legacy of failed justice.

Integration did not happen. The effect of my father’s and my foray into those white schools was not more equality but white flight. Largely white schools became largely black, and Latino schools were stigmatized as “bad” and never had a place in the California good life.

It’s partly because diversity can be managed — or minimized — that charters have become the public schools that liberal whites here can get behind. This is in direct contrast to the risky, almost revolutionary energy that fueled past integration efforts, which by their nature created tension and confrontation. But as a society — certainly as a state — we have lost our appetite for that engagement, and the rise of charters is an expression of that loss.
