Repeal “No Fault” divorce laws. For contested divorces, make the party initiating the proceedings forfeit any claim to the marital assets if they can’t prove fault by the other party. Eliminate child support and welfare for unwed mothers who are not rape victims. Eliminate child support altogether, as long as women have the option to terminate their pregnancy, but the men do not have the option to force them to do the same.
I think you need to grandfather child support. I would restrict child support to the number of kids you had when you applied and then no increase for more kids.
Perhaps we could get a waiver of father’s responsibility if they decide unilaterally to have the kid.
