This generation has an unrealistic idea of where they should live (some of them at least). It's not like the people who bought houses for 100k in the Bay Area in the 1970s were making 300k a year working for Facebook. There's nothing stopping people from moving to Ohio and getting a less well paying/glamorous job but buying a house.

The solution is there today, people just don't want to take it because they want to live in SF/NY... When houses were affordable in those areas, they didn't have the cachet they have now.
