Which countries?

And it's actually become far, far more common for children in the US to remain in childhood homes past the age of majority. According to Pew Research, half again as many young adults still live in the parents' home as did the previous generation. This is largely a function of escalating housing prices & low-paying gig economy jobs. In short, economic dysfunction.

Your essay begs the question that children remaining in their parents' homes into their 30s or 40s is somehow superior to finding homes of their own.

Then you characterize making 18 year olds—who are adults, not children—move out "child abandonment"!

Really, dude?
