Cause I was staying on topic. OP wasn't bringing up a "solution" to anything, there's no world in which children just suddenly go along with arranged marriages in a culture where all their peers are getting to make their own decisions on that shyt.
If you can't pick a woman who wants to stay faithful with you and build, that's honestly on you. There are still such women out there but 99% of the threads on women around here ain't looking for that shyt, they keep focusing on attributes that don't have jack shyt to do with raising a family together.
If you want families to be more likely to stay together, then we need to work on improving the financial situation of Black men. Get folk back into the Black church, and churches that actually build and maintain community rather than the megachurches and telegrifters. Keep black men out of the justice system, which is a combination of education reform, justice reform, and economically diversifying communities so the worst-off and most dysfunctional aren't all stuck together with no peers in a better situation. And work really fukking hard on mentorship, which means every man whose worth a fukk getting involved in relationships with young men and helping build them up. Same thing for the women too, of course.
It's no easy solution, and it doesn't fit in with your apocalyptic fascist fantasies, but unlike your hopes it actually has a chance of working.
