Yeah, housing. It's the big issue of the day here, and you can see how much it affects our culture.

Basically we created a mortgage system that only works as long as property values continue to rise, which created a lot of political will behind "improvement" measures like eliminating public housing, like we did in the early 80s.

(see http://www.wraphome.org/downloads/without_housing.pdf [pdf] for a fascinating study on the origins of modern homelessness)

I'm doing some experiments with cooperative housing and income-sharing right now, which slightly mitigates my contribution to gentrification, but something else is needed, and I'm not sure what.
