What that means is that it takes parents and extended family and the close-knit community you'd find from a church and from schools, for example. Millions of people do this today. It's odd to see people think this is a revelation or something.
I'd agree and my comment is more of a critique on the evolution of American society leading away from community building. Whether it be subtle things like suburban homes with giant privacy fences or larger topics like the affordability of housing to be able stay in the community you grew up in.
I'd much rather see policies towards solving these problems versus one that has the government getting in the middle of my marriage or parenting.
