They could start by eliminating the baby factory incentives.
The way the legal system is structured now, you can't get there from here.
The Courts will hold that every one of these worthless indolent people have a right to create as many babies as they want.
I have long suggested that the system offer money incentives to get free vasectomies and tubal ligations for anyone that wants them.
But making them stop? Not going to happen.
