>>2557753A lot of right-wing propaganda is demand lead. Stupid, low-openness, low-social-trust people prone to negative sum thinking like to have their stupid, low-openness, low-social-trust, zero-sum prejudices confirmed. It's not just that they're stupid and gullible, it's that you're starting with an inbuilt advantage. If you hate new things, think other people are naturally evil, that the world is naturally hierarchical (even if you find yourself a total loser in that hierarchy), etc, it's very easy for right-wing propaganda to work on you and much harder for left-wing propaganda to work.
The real decisive tiebreaker here is economics. Every economist agrees that, outside a tiny range of circumstances, tariffs are the most retarded thing in the world. Pre-Trump, a good chunk of right-wingers with more of a libertarian influence would agree. It is, quite literally, basic economics.
Well, the most prominent right-wing politician in the world has a tariff fetish, so what do right-wingers do? Defend tariffs. Defend tariffs in actively retarded ways. (Have you ever considered that maybe it's good to make everyone poorer?)
For all the money a chunk of neoliberal inclined people have thrown at economic propaganda, which has been broadly successful when it comes to taxation and nationalisation (which are "pro-social"/high trust ideas), it all went totally down the drain on tariffs. "I don't like foreigners and think we should stick to our own, the world is zero-sum and if they're winning we must be losing" as a stupid, ape-brained prejudice proved more powerful than all the money in the world.
It should, however, be said that "non-left-wing" left wing propaganda has been very successful. The average young person is incredibly socially liberal and the cultural norms of socially liberal communities (say, "the LGBT community") are overtly socialist, often communist sympathetic. The right are a loud minority of young people propped up by middle aged and old people.
