The USSR and China were much more widespread examples of eliminating landlords, both were vastly successful. They were third world countries with terrible conditions, both became global superpowers, all-the-while providing housing at a vastly more reasonable rate.

China has since regressed on this, and they're starting to feel housing troubles as landlords destroy the housing market through scalping, but for a long period they were improving.

The best example is probably the USSR during the 70s. Still a country with vastly less wealth than America, recently developed into a global superpower, but still was providing housing to citizens at an average of 5% of their income. America has been operating very consistently in the 30-80% range for a long time.
