It's pretty hard to make it up in volume with housing. So it behooves builders to build houses that are as profitable per man-hour as possible. The solution that worked before was government housing. It increases the supply, which lowers prices. It also can put in government-managed caps for price, which puts downward pressure on the prices charged by private homebuilders. This in turn puts pressure to not build as many luxury homes, because the market for them becomes people who want luxury homes and not people who want homes and are willing to buy a luxury home to do so. And that causes an increase in capacity to build less luxurious homes because the house you can sell now is generally more valuable than the house you can sell 3 or 6 months from now.

This isn't an easy solution. It took us 40 years to get into this mess, and it's going to take a good while to get out of it.

Edit: also, capitalism tends to put pressure towards profits now more than more profits later, and generally gives no incentive for making the world a better place. Capitalism directs you to charge as much as the market will bear, and the smaller the supply of new homes, the higher a price the market will bear. So this is absolutely a failure of capitalism, and it's unlikely capitalism will fix it. Only a fool (or an altruistic, and capitalism paints both with the same brush) would go out of his way to devalue his own product. This doesn't apply to Costco because, as I initially pointed out, making it up in volume is well within their capability.
