I live in amerifatland. They're building new houses all the time, everywhere I look, entire complexes of them. "McMansions," we call them.
I make average US wages, have my entire adult life. I cannot afford a house in my city unless I buy a literal ruin in the ghetto. The suburbs are far more expensive, and that's where the McMansion complexes are. I don't know who's buying them, but it isn't me and likely never will be.
That's because we regulate growth. Seriously. It's exactly the same root cause. Have you heard about why zoning drives up housing prices?
