What does the last global debt crisis (which was caused by central banks around the world keeping interest rates incredibly low for a long time, which allowed housing debt/speculation to balloon massively, and then tightening suddenly) have to do with the failures of the free market to develop sufficient housing? And in many major cities, things like zoning are preventing developers from building nearly as much housing as they’d like. I guess I’m just kind of baffled as to how you’ve reached the conclusions you have. I’d love some clarification.
