I pretty much agree with everything you’ve said but would like to put a large asterisk by this last sentence of yours…
I’m blaming the division on the commies in our education system and media that are former hippies taught by the Karl Marx philosophy. They love to force people in different socioeconomic, ethnic and gender groups which creates a bunch of divided groups waring for power. You’re not an individual anymore, but part of some identity group.
The leaders in the US (and world for that matter) of today remind me of the rich , woke hippie son that took over dads successful business he started from scratch and turned it into an unsuccessful mess.
