I think we can blame the late 60's for the start of rampant drug use but I agree with you regarding the devastation of the 70's on that subject. Destruction of the family is not limited to the 70's. Not sure when that started to happen.
When the feminists began the crusade for ALL women to avoid childbirth and/or leave their kids at home; and replace them with a job.
Destruction of the family is not limited to the 70’s.

Most definitely agree with you on that point. The progressives set the wheels in motion on destroying the family well before the 1970s, but the train really picked up speed during the ‘70s, and it has shown no signs of stopping.
