Ok, there's a bit of a mention there, but they don't seem to consider it the foundational issue. They mention education costs for several paragraphs - education costs would likely not be so high if real estate costs weren't so high.

Fewer desireable/high paying jobs gets several paragraphs, but again, this would be less of a problem if rents weren't so high - people would be able to live on the incomes available. High real estate prices are sucking the oxygen out of the rest of the economy.
