Did people act like this in the 70s too when we had stagflation, mass unemployment, gas rationing, Vietnam, Nixon, etc. to contend with? I ask that sincerely because I wasn't around then. The US got a ton of cool music and cinema during that decade (disco and soft rock excepted) but the rest of it sounds even worse than things are now.

People acted like this constantly, the 70s are incredibly sanitized in the popular imagination. A government strike force murdered 4 student protesters at Kent State in 1970; Boston had 40 race riots between 1974 and 1976.
