After 1970: The dividing line

Chateau Heartiste writes:

1970 appears to be the foremost dividing line between “good, functional, beautiful America” and “bad, dysfunctional, ugly America”.
So many social ills explode with a ferocity sometime around 1970, and continue exploding right to the present day. Count them out.

Single momhood.
Obesity.
Male unemployment.
Divorce. (Appears to have plateaued recently, thanks in part to fewer marriages.)
Total marriage rate.
Alternative mating arrangements.
STDs.
Abortion.
Low White fertility.
Astronomical debt.
Crime. (Though crime began a long decline in the 1990s, thanks in part to mass incarceration and internet porn.)
Feminism.
Equalism.
Multiculturalism.
PC neoPuritanism.
Anti-white and anti-free association Acts.
Wiggers.
SJWs.
Slut parades.
Fat acceptors.
Credentialism.
Bryan Caplan.
$22 trillion wasted in malign “war on disparate outcomes”.
Hijacking of every major public institution by the Left.
Diversity graft.
Welfare replacing workfare.
Parasite shamelessness.
Surveillance nation.
Manboobery.
White population displacement.

It all seems to have started around 1970. Read more here.
