> What bothers me is not that the poor stay poor and the rich stay rich. That's pretty much the history of the world, and it's unlikely to change any time soon. I know that was said in passing, but I want to point out that it's not true: Economic mobility exists, and the amount of economic mobility can and does change. Economic mobility has decreased recently in the U.S., but let's not accept that as a fact of life. We can do better, and we can innovate ways to do better than ever (e.g., by providing quality education to disadvantaged children).
