The cause of homelessness is lack of housing.

The rich...should beg the poor to forgive us for the bread we bring them. Healthy people sometimes feel they need to beg forgiveness too, although there is no reason why. Maybe we simply ask forgiveness for not being born where these poor women have been born, knowing that if we lived here too, our fate might well have been the same.

Children sometimes understand things that most grown-ups do not see.

But what is now encompassed by the one word (“school”) are two very different kinds of institutions that, in function, finance and intention, serve entirely different roles. Both are needed for our nation’s governance. But children in one set of schools are educated to be governors; children in the other set of schools are trained for being governed. The former are given the imaginative range to mobilize ideas for economic growth; the latter are provided with the discipline to do the narrow tasks the first group will prescribe.

By far the most important factor in the success or failure of any school, far more important than tests or standards or business-model methods of accountability, is simply attracting the best-educated, most exciting young people into urban schools and keeping them there.

What I tell these young people is, the world is not as dangerous as the older generation would like you to believe. Anyone I know who has ever taken a risk and lost a job has ended up getting a better one two years later.

I do get scared about the physical danger from drug dealers. But it's not in the same league as the danger I feel eating an $80 lunch with my privileged friends to discuss hunger and poverty. That's when my soul feels imperiled.
