A few possibilities:

• The kinds of people who radicalize on the right seem to be more rural, less smart about money, and more fearful of economic and cultural changes hurting their way of life. Rising gas prices and inflation hurts the person with a $800/month payment on a truck that gets 10 miles per gallon, on top of keep a gun hobby that costs thousands of dollars for all the latest parts and ammo. We think "time to cut back on meat and finally pull the trigger on that hybrid/EV". They think "Soros wants illegals to replace our jobs and make us eat bugs." No, it doesn't make sense. It doesn't have to.

• These folks may be class conscious in a sense that they see "elites" as the ones holding them back, but they don't recognize the bourgeois on the right. They love Elon Musk and Trump and hate Soros and anyone from LA or Hollywood. They may also see this as "a few bad ones" or "not real Capitalism" and fall into the same mental trap Democrats do that if we just get rid of X everything will be fine.

• They think their "culture" is under attack, and they think they are losing some Culture War. Every time a major TV show, movie, or video game has non-white characters or anything LGBT or anyone this isn't white and Republican like them they call it "woke" and freak out. These are not people that can simply "not watch" because to them they need control over ALL media. They can't tolerate some media catering to people besides them!

I think in addition to what MayoPete said there isn't really any media to speak of out there telling people shit is bad and it's because of marxist explanation. Instead we have a right wing media that tells people shit is bad because of immigrants and the elites and a liberal media that tells people things are fine stop worrying so much. Unions are basically non-existant and third places no longer exist so unless you actually go looking for it and actually do some reading the closest thing to class consciousness you're going to land on is fascism because it's the most readily available in life.
