This is really not very hard to understand. Families that can not afford to stay together split apart. Children are then mostly raised by a mother that mostly gets her money from men that mostly want to screw her. Mostly there is no Dad around cause if Dad is around then Uncle Suger Daddy (Uncle Sam) will not give she goodies like food stamps, welfare checks, eraned income tax credits, etc. Plus Dad is pretty much useless cause there ain't no jobs. And why are there no Jobs cause yall free traders sent them all over seas.
Hope this helps to explain things.
Jobs/work are a vital part of keeping a cmmunity moral and together. Without jobs, in one or two generations you have rampit drugs/prostitution/crime.
I know I live there.
There is a funy twist to things that I haven't figured out. These societies turn matrearcial (females lead) and men of means are reguarded the same as men of no means, which is to say not highly reguearded at all. The women develop characterists that are decidely male. Fighting, drinking, gambeling, chasing younger men. All very sad.
So if "free trade" is what caused the moral collapse, why was there no moral collapse in the poorer communities in the 1930s (as you claim)?
