Fair, I did not see that :)
I would assume that you can take virtually any society that goes through rapid change over the course of a few decades and make all manner of cherry-picked charts like this. Just ignore all the charts with shapes that don't fit your hypothesis (like they show divergence way outside 1971, or gasp, they show positive changes!).
Honestly, I find the attitude that the best times in America were 50-60 years ago to be baffling.
So let me ask it this way: you can be born at a random place as a random person in America. You can't control your gender, your race, your sexual orientation, your intelligence, your socioeconomic standing, your family, your health, nothing. The only thing you can pick is the year.
What year are you going to choose?
I'd love a serious answer too. I never seem to get one that supports the idea that America's best days are behind us, but maybe you'll provide some reasoning.
