And they don't believe in the system because they were left behind, by both parties. Reagan broke the unions, Clinton globalized the jobs, et cetera, going on for more than three decades. For a while, you could fool people - yes your service job pay is stagnant, but goods are cheaper. Meanwhile the divide between the rich, who took all the benefits from globalization, and poor grew enormously. 35 years later, a blue-collar worker looks at the situation with despair and is told they are "privileged".
Burn it all down I guess.
And let's be clear that Trump will not fix things one bit. Tariffs are proposed as a solution (maybe they are part of one) but in the short term will not bring back the jobs and only make goods more expensive. Opportunities such as revitalizing the economy by revitalizing the energy infrastructure, while addressing serious environmental problems, will be missed out on. The likes of the people who know the problem, talk about the problem, and propose actual solutions do not get elected. In the 2020 primary, Bernie Sanders was "too extreme" and Elizabeth Warren was "too intellectual". Instead you get everyday-man Joe or some other anointed, fits a particular demographic, leader... or a demagogue like Trump.
I don't see a solution. Democracy is not set up for finding intelligent solutions. Historically, it took major trauma such as a world war to change directions towards equalizing and benefiting all of society. So while I can understand the vote to "burn in all down", it was extremely foolish - we will all burn and it will be extremely painful if not lethal.
