Earlier quoted context omitted.
This is extremely silly. Prices are high because we don't build enough houses which is mostly because it's really expensive to build houses, then the houses we have built are all owned by empty nesters and people with 1 - 3 investment properties. Everything else you're describing is completely ridiculous.
> which is mostly because it's really expensive to build houses, Assuming you're referring to the typical high CoL areas, the shortage has very little to do with the expense of building. The zoning laws don't permit sufficient supply in those areas. And that's quite unlikely to change (at least quickly) because anyone pushing such reform would be obliterating the average Joe's net worth.
Only in a purely illusory sense. Suppose you have all your net worth tied up in a house. If your house magically vanished, you'd have nothing but your job.
The price of houses falls to $500 and you potentially go bankrupt. Then, you buy a house for $500.
You, personally, are now better off than you were before. Some examples:
---
1. You have $200,000 of equity in a $700,000 house. After the price drop, your net worth in dollars has improved by $300,000. Your net worth in "stuff" has risen dramatically; you kept your job, and now you have 100% of a house instead of having 30% of a house.
2. You have $700,000 of equity in a $700,000 house. After the price drop, your net worth in dollars is down by $699,500. Your net worth in stuff is unchanged. Assuming you always need to live in a house, this will never have any negative impact on you. You retain the option to live in the house you have (which leaves your life unchanged), and you also retain the option to sell your house and use the proceeds to buy another house (and this option looks a lot better than it used to; given the crash in prices, you can probably afford a much nicer house).
3. You have $200,000 of equity in a $700,000 house. You also have $15,000 of "equity" (resale value) in a car that you owe no money on and bought for $50,000. After the price crash, you lose your house and your car, and then you buy another house for $500.
Replacing your car will cost you $50,000. You are in a similar position to the guy in example (1), but $50,000 poorer. So now we ask: was it better to be $500,000 in the hole on your house before, or to be $50,000 in the hole on your car now?

There isn't a way for the average Joe not to come out ahead. There is a way for someone else to lose out on the price crash: if you had more than one house before, you lost everything on the houses you weren't living in. But that's got nothing to do with the average Joe.
