The doom cycle of the last 50 years:
- Fed lowers interest rates to increase demand. Prices go up, only the most well off can afford.
- Fed goes back to increasing rates again. Demand goes down. Prices generally don’t decrease all that much really, they just stop going up, and higher interest rates are what stop more from getting a house.
Literally nothing for supply side. Our society has decided to leave housing up the The Fed to tweak demand.
