Nobody’s stopping people from forming families.
I find most writers along these lines, supposedly from conservatives, are actually from young DC think tank married, white fathers who advocate massive government subsidies for their children.
One of the few things we should promote in this country is large nuclear families.
The downfall of the nuclear family is a disaster for Western Civilization. Unmarried mothers are the most dependent on government services.
Very few white fathers get anywhere close to the return from the government that they put in.
