Interesting strategy, and likely one that has some merit. Though, I’d point to similar problems in Japan where it’s not rare to have incredibly tiny homes/apartments, but a very high rate of youths staying at their parents’ places well into adulthood.
The US has reached around 50% of young adults continuing to stay with their parents beyond school. It’s up to a similar rate as the Great Depression era. We’ve priced our kids out of independence to try to satisfy a few billionaires’ desire to be ever richer.
