I'm not sure if you saw "60 Minutes" the other evening, but one of the stories was about Hope Chicago, funded by a billionaire, which is doing extraordinary work sending kids attending high school on the city's South Side to college. (Watch the story. It is amazing.) I was thinking about it because it makes the point that if you want to solve problems like poverty, homelessness, and violence, one of the best ways to do it is by expanding access to education, and improving the odds of the people who attend college. When my dad died a few years ago, that's one of the things he wanted to do, albeit on a much smaller scale … but last night I got a reminder of how hopeful and powerful that can be.
