I remember a piece in the San Jose Mercury News (I've referenced this before, but haven't been able to locate it. I expect it was never put online) from back in 2000 about full-time public school teachers living in San Jose homeless shelters because they couldn't afford to rent or buy in the city where they worked.

I expect that in expensive areas, teachers still need to commute hours to work if they want to teach there.

That's appalling to me. Given that teachers, second only to parents, have enormous impact on the development of our children.
