Average income in 2021 $65,000, well short of the $80,000 to equal 10% of the house. Also, there has been a large increase in other expenses. Most households had a single earner, leaving another adult to generally raise children. That's much rarer today. Two car households, higher utility bills, etc... The evidence is pretty clear that money doesn't go as far today.

The boom in housing prices is also a temporary anomaly. That's only half the reason young people can't afford them. The other half is NAFTA and globalization and trade agreements, etc. Those were all done by politicians for corporations. It's easy to blame Boomers because you read an article that did that very thing (it's common in news to stir cross generational resentment). It also lets the politicians off the hook. Remember that next time they say the presidential candidate of whatever party you prefer will actually help you. Unless you are a corporation, that's unlikely.
