The woman leaves the man most the time,because she knows she can take care of the child alone.
Why? Because the state gives her all kinds of welfare and tax breaks.

Then she gets remarried , and has more kids by different men.She gets college grants etc.
The point of the system is they cant take care of themselves.Show me one woman that hasn't had government assistance of any kind.

Imprisonment for debt is constitutional.
Force payments are unconstitutional , otherwise all force debt payments are constitutional.
Force health care insurance is unconstitutional.

Also Your agreement is under whatever the law was at the time is was agreed.Most the times the court try and stick you with the new laws of probation and shit.Retroactive judgments and court rulings are unconstitutional.
They refuse a persons right to council.
They force you to court, and make you pay the court fees.
The woman never has to pay a dime towards her own case.
The hold you in jail until you come up with the bail money or arrears.
They dont give you a conventional bail.

The Whole System is a waste of tax payers money . It brings in no revenue , but has a whole system of cost built around it.
