What's funny is I was just thinking this same thing. That is, this last election seemed really divisive! Far more than true differences. When we're fighting we're easier to control.
We have had the same thing in the UK where the EU barely made it into peoples top ten list of priorities to completely dividing the populace and subsuming every other political issue for the last three years.
I'm not totally sure whether it amplified the differences or took the lid off some rather nasty but hidden opinions. Either way the result hasn't been positive.
Their solution to this is 1) divide and conquer and 2) scapegoating.
Which is why a racist boomer robot took your job and gave it to a Chinese millenial mexican illegal immigrant on drugs.
