Education inequality

Today's NY Times carries a story about several studies, collected by the Russell Sage Foundation into a book, about the rising inequality in education based on income. It's interesting, and that's because the recent studies show that family income, not race, is the biggest dividing factor in achievement. The first chapter is available online, as are the tables. They're worth looking at (and much better than the partial table published in the Times). Here's a screenshot of one table, illustrating enrichment expenditures on children by income quintile:

Take a look at the tables, and the first chapter. I found them pretty depressing. But if you draw another conclusion from them, let me know by commenting.
