My bigger question would be how much housing prices and rent would go down. They tend not to go down as much due to subsidies and stickiness. Absurd housing costs are the key thing keeping me away from the bay area, but it is so bad I'd need a 50% drop to make it close to reasonable.
They won't go down while Chinese and Indians are moving in.
so what about the greedy white people that sell to newcomers at inflated prices in turn pricing out their "own"?
What precisely makes you think it will be 10x worse?
