What’s the point of focusing on one aspect of the world?
Taken as a whole, the 60’s were far more intense and violent. The Vietnam War. The draft. The Cuban Missile Crisis. Racial inequality and protests. Several major assassinations. Nixon in the White House. And that’s just the US.
The world is net-better even if certain areas still need improvement. But there’s really no point to hyperfocusing on just the things that are worse.
