With all due respect to the people who think this is _the_ defining issue of our generation, I think you are wrong. Climate change is the biggest issue of our generation, period.
By housing, we really mean land use. We inherited from our grandparents a society built around cars, and restrictive zoning that prevents society from rebuilding away from cars. Just look at the zoning maps, how much of San Francisco is limited to 40 foot height limits (35 foot if you’re building a single-family house) and 1 or 2 homes per 2500 square feet parcel.
