I still think your plan is no more likely, and far less helpful to the country (and to families and children) than simply eliminating the welfare. If men knew they’d have to support their children, if women knew there were no freebies for producing a baby without being married, people would be more responsible.
How do I know? Because that’s the way it was before we removed those incentives.
It was not a plan, merely a thought expressed publically. In my lifetime American morals have completely collapsed. It is not that we did not have immoral behavior; but it was not extensively embraced as a “good thing.” I do not see anyone having effective powers of resistance. So it may be best to adapt to the rot and try to control the acting out.
