In the same way that bonds compete for investment dollars that would go into the stock market. The stock market has been going up only for AI companies, meaning all the money is flowing there.
If AI didn't have the hype, those marginal investment dollars driving up AI stock prices, they'd be flowing in to other uses of the capital, some of which I believe would be far more productive.
That presupposes we want home building to be driven by investors who are looking to make the highest ROI.
Isn't the healthier option that people who want homes get them built? You don't need a general investor in that loop, except if we're talking bout "mass housing" but even then, those are generally property developers and they are unlikely to use those dollars for non-property development.
