You want to know why Gen X and Millenials are so nostalgic for the recent past and angry at the world today.
It's because we got a glimpse at a world of promise... a world that wasn't controlled by the dumbest, most selfish, greedy, narcissistic people on the planet.
We were worried about things like the giant fucking hole in ozone layer... and smart people got together and solved the fucking problem... It gave us hope, it promised a better tomorrow.
Now we remember that... and look at what's been done... and we mourn the loss of that hope, that promise... that future.
