Inflation adjusted household net worth rose 30% under Trump, under Biden it was negative for a time, but has finally rebounded to a meagre 0.7%. Research shows that culture war issues are most important to partisans with long commitments to their party, although I don't discount the various factors you've listed. But to give an example, on the ground investigative reporting by somewhat heterodox reporters following the Youngkin Virginia Governor's race found that few were aware that a trans student had anally raped a teenage girl in Loudon County. Instead, they found the fact that many parents believed their kids had been harmed by unnecessary school closures and mask mandates and this appeared to be decisive factor in the Youngkin victory.
In a CNN segment interviewing a panel of Virginia voters an interviewer asked "What about January 7th?"- to which one women on the panel replied "What about it?"
The school issue seems to be the one thing which is penetrating most- and we know that the sheer volume of immigration has voters in America annoyed. On the former, there has been a real grass roots movement springing up in many areas, and on the latter issue, it's been particularly critical in shifting historically high African American support to Trump, as many African American communities in places like Chicago have seen resources they have fought tooth and nail for quickly reallocated to serve illegal immigrants needs.
And on the subject of migration, don't you see that the pandemic changed people's behaviour in relation to employment? Many faced their worst fears and realised it was nowhere near as terrible as they thought. Many retired early. For many mothers in two income households it inspired a shift towards fewer hours spent at work and more spent at home with their children. And for many it involved a shift towards remote work.
To begin with, Biden tried to mimic the tighter labour markets seen under Trump, but the corporate overlords quickly started to complain. It's one of the primary reasons why they are shipping workers in such numbers- because the pandemic temporary changed the negotiating relation between employer and employee decidedly in favour of the employee, through market dynamics and behavioural change. Plus, a lot of those job vacancies are fake- check Google and you'll find numerous articles on the subject. In addition, there have been some excellent articles focused on companies like Amazon, where despite thousands of job listings for a particular region for a given period, the actual number of employees employed shrunk per quarter.
Most employers are interested in the top 10% employees for a given task, whether its case resolution in admin or line worker throughout. In some instances, the top 10% in a workplace can account for 50% of all productivity- roughly following the Pareto Distribution. Most employers are willing to wade through application and work trials to get to the 10%, and the fact that innovation has made the process considerably cheaper means it has distorted the appearance of the jobs market and claimed vacancies.
I agree that the Gell-Mann amnesia is lifting. Here in the UK, an increasing number of workers have been exposed to the more ideological version of DEI training. In a Dynata survey conducted for the Free Speech Union, 31% of respondents stated they had left a previous employer because of the uncomfortable workplace created by DEI training, and the figure rose to 43% for Black British and LGBT respondents- proving that DEI is worst for those it purports to want to help.
Let me guess the book in question was 'This Book is Gay'? I've seen some truly awful justifications online which completely misrepresent the book. Birds and the Bees mechanics on how reproduction works can be offered to children as young as eleven, for the simple reason that it is the age when an admittedly tiny percentage of girls can get pregnant if no education offered- but it's the biology only. What heterosexual biological sex education does not do is tell 12 year old kids how to join a dating app so they hook up with adults, or provide lurid graphical illustrations of the things they might want to try when they do.
