The point of this analogy is that we as a society have become really soft in raising kids. If you don't do the dirty work and discipline by the time they get to be teenagers they are gone. Forget about instilling social virtue and respect for law at this age because they are far too gone.
The Democrats and elites don't want us to use patience and firmness in raising our children because they have a vested interest in disorder hence their disdain for the nuclear family. Chaos is control and they have already wrestled control from public education by teaching about rights instead of what is wrong or right and now they want to sever that last cord between the child and parent.
Did you just read Starship Troopers? That book had great philosophical points regarding children/citizens.
