Communal living is highly overrated. If you're a young and capable person you'll be shouldered with responsibility and live under the thumb of your elders. Not a dignified existence. I barely tolerate my own parents, I will not tolerate my extended family demanding things from me.
It's highly underrated by young people who don't like the idea of living with their parents. Ultimately, the cost of this is shouldered by day care fees, parental leave, social security checks we cut to old people, and less efficient living spaces; problems which were ok in an era of gdp and population growth, but in the era of stagnation? We'll see.
