Utterly missing from this screed is so much as one practical, useful suggestion for how to provide more affordable housing. The bottom line is that the only manner in which this can be done is through government funded subsidies. The best systems I have seen are to build rental housing using tax credits with strict limitations on rental rates and to build subsidized housing in which appreciation is shared between the government and homeowner. But both have flaws - and getting that below market rate apartment or subsidized house is like winning the lottery, causing anger and corruption. 

The real solution is more equal distribution of wealth. If those at the bottom earn enough to buy a decent home they don't need subsidies. In the 1950s and 60s the problem was solving itself. Home ownership rose steadily. But then we entered the new age of the wealthy, where tax cuts at the top and a cult of greed have shifted income and wealth to the worst imbalance in history.
