It was a pale reflection of the Sixties

Most of the changes took place in the 1960s during the Hippy era; by the 1970s the damage had been done,

The changes in consciousness that occurred during the 1960s were an existential threat to the entrenched powers; after Nixon took office in January of 1969 he pulled the plug on the economy and kept people scrambling to survive.
The Establishment is well aware that, historically, revolutions almost always occur during periods of rising expectations. I remember Republican President Gerald Ford telling the American people that we need to
lower our expectations; a dead giveaway.

It required years of concerted effort among the government, corporations, and media to get the consciousness level of the American masses back down to the level of the 1950s.
Keep the people struggling merely to survive and other considerations take a back seat.

Pedophiles are a case in point. When the Supreme Court legalized pornography under the Warren Court, some of the bluenoses were offended, but for a while all porn was legal, and there was no such thing as "kiddy" porn per se. Children featured in porn were viewed as just another form of expression.
Later, in a sop to the prudes, children were excluded from porn, and the powers-that-be then had another potential scapegoat to distract the people.

As Supreme Court justice Kennedy stated: "The government has a vested interest in regulating the sex lives of the citizenry."
How, or why, that clown remains on the nation's highest court is a textbook example of where the Truth is, and don't look for it there.
