>The only people who can say they didn't understand that would have to be people who not only didn't know what tariffs were in the first place, but who also didn't bother to listen to the many many people trying their best to explain it to them
anti intellectual sentiment runs deep in many parts of US society. Having experts out explaining things - particularly via news media outlets - has unfortunately become an ineffective tactic as a result. There are many people, across different areas of US society, that reject any expert explanations in favor of their own beliefs, or things they read that re-enforce their beliefs.
We live in an age where 'vibes' and anecdotal experiences override facts based on well gathered evidence and history.
I believe quite strongly the average Republican voter is heavily weighted toward dismissing public experts out of hand.
All this is to say, I'm surprised that didn't have much impact. It should have completely destroyed his campaign to be honest, as many of his actions should have, but this was an indisputably bad idea from any reasonable economic standpoint.
>Only his ego is getting in the way now
I largely agree with this. I will only add that I can't tell where Trump ends and his donor class setting the agenda begins.
