Many women have divorced themselves from procreation with abortion and contraception.
In so doing, they have rendered themselves no more than paid companions to the men they are with, and no man is faithful to a paid companion.
When women divorce themselves from procreation, they often say that this lets them be as unencumbered as men allegedly are.
That position affirms that men are viewed as divorced from procreation, i.e. from parenthood, in all respects other than financial.
That, in turn, is the root cause of all the degeneration you tracked.
Just as each lock is in the shape of its key, each problem is in a shape that fits its solution.
With regards to this problem, the solution is to restore fatherhood.
Lot of truth in that.
