That's a very very partial picture of it. There's a lot of hate about social change, people are terrified of trans people and that has been effectively turned into a culture war issue.

Also your economic story doesn't hold water. The Biden administration successfully placed tons of factories all over the country with tax incentives for clean energy, but those factories could never trumpet what they were doing because hate for Democrats and for Biden and for clean energy is stronger than any desire for jobs. Similarly the destruction of the CHIPS act and its unpopularity in rural areas also shows that the economic opportunity aspect is just an excuse for the cultural hate that has been worked up.

The best way to understand a Trump supporter that I have come to is a person that hates Democrats more than anything, and will do anything possible to bully them, including the economic destruction of the country. I have a lot of family like this, and for years I thought they were just joking or exaggerating about their hate, but the past year has shown me that they were earnest. It's not the 1990s anymore, this is a visceral culture war above all else.
