Government will have to be better because it won't stop getting big. That's because it's common to have one baby and quits. After two generations of one child families, there is no kin group left. A kid still has two parents and four grandparents but there is no sister or brother. There are no aunts. There isn't a single uncle. No one has first cousins. Who do you turn to when you leave home? The kin network collapses when one child is the rule. Government steps up, not in loco parentis but in place of kin.
The chart is from The Federalist: "Why we lose with only two children per family".
