> You'd have no trouble buying a home on a $30k income 20 years ago. They could barely give houses away back then.

I made a bit more than that 20 years ago and can guarantee you it wasn't anywhere near enough money to buy a house. Finding affordable apartments to rent on that salary was difficult enough. I lived in New Orleans, which wasn't a high cost of living city at the time. Maybe if you lived in the middle of nowhere that would be doable, but almost certainly not in a city.
