Yeah, that was a pretty bad decision, but the bigger issue is still a population that votes based on misinformation and 'alternative facts'. Until that is resolved, if it even can be at this point, then this tribal and sometimes cultish behavior is only going to become more prevalent, in turn doing more damage to the country.
Personally, I think we've started on a path to self-destruction that can't be reversed.
Oh, I mean the US specifically. I'm optimistic the other western powers won't go down the same self-destructive path the US has chosen, largely because they have much better public education pre-college, and much more accessible higher education.
I expect even China and India to start improving drastically in all the ways that matter as the US continues to downlside.
