I'm a bit confused, this article seems to only look in depth at rent control in San Francisco? San Francisco and any city in California is a major anomaly compared to other cities in the world. For example, rent control in Montreal works fairly well for renters and has kept the city affordable for the middle class while residential construction still booms.

Housing in Montreal is cheap compared to the rest of Canada. Rent control "worked" because there was little upward pressure on rents there.
