Some good points, and a good insight into the Trumpist mindset, but a lot of things left out, and some direct contradictions.
For a start, the slides start out by mentioning three highly popular, expensively produced, wildly commercially successful movies that portray country people as Good and city people as Bad. Then, a while later, the slides complain that popular entertainment supposedly focuses only on city people and never mentions country people, except to make fun of them. Taken
together, these two parts of the slides are pretty ridiculous.
While the slides list some differences between country people and city people, they never really explain why the city people's traits are supposed to be bad. What, city people are supposedly turning atheist and leaving their churches? Why should anyone have a problem with that? A lot of the complaints come down to saying that, from the perspective of country people, city people are kinda weird. Well, so what? Since when is being kinda weird some kind of major crime, or a legitimate reason to hate someone?
The main sources of tension between country people and city people are not about city people being "arrogant" or some such nonsense. They are about three things:
1) As the slides note, country people and city people are often different.
2) Country people often hate everyone who is different from them.
3) City people, like most human beings, often don't like it when other people hate them for no good reason.
As for the economic stuff, yeah, that's true, but it's neither anyone's fault, nor can anyone do anything about it. It's part of the nature of things that in a large, complex economy, wealth is created by a lot of complicated processes that are more likely to happen in cities than in the countryside, because they involve interaction between a lot of people. Therefore, rural areas are usually poor, unless they are either close enough to the nearest city to be well-integrated into the city's economy, or lavishly subsidized out of taxes paid by city people and city businesses, or temporarily lucky with the one or other local export.
Donald Trump can't change that, and neither could Kamala Harris. Or you, or me.
For the record, I myself spent most of my life, and currently live, in the suburbs, although I've also lived in both rural and inner-city neighborhoods in the past. Though I'm enough of an introvert that I'm not sure how much effect my surroundings really have on me.
