What would stop this behavior real quick is to have nobody paying for it.
I will gladly pay for condoms and BC pills. Otherwise, they are on their own.
What stops bad behavior is living with the consequences.
The real lesson is that innocent people will suffer to learn the lesson.
In years past, they didn't have to. Now the government can go after the father for money the government paid to support his kids...they can also go after the father for past payments made to the mother..
..all those that don't like SS blame the government that made it mandatory. Not the people that were forced to pay FICA. Yell to congress not to us old fogies that had to pay for decades into a program that took the money and redistributed to their friends for buying votes...
