People do not care enough about their day to day livelihood to vote in their own best interests, forget about the interests of the broader community. They don't care enough to understand the relationship between who is in office and what happens directly to them and their family. They fall for mis- or disinformation that takes advantage of their emotions in the moment, and end up shooting themselves in the foot, over and over. To be fair, millions of dollars and technical resources are invested in creating and disseminating that disinformation, as well as in weakening the public education system so students are not taught critical thinking.
Black and brown voters, poor voters, veteran voters, women voters (gee - that adds up to a significant majority, doesn't it?) may not respond well to being warned they were about to vote against their friends; may not like to hear "I told you so". It will take the government coming for them or someone immediately close to them for them to understand, and then it will be too late.
I have no idea what you mean by the "clubs of structural economic violence". Democrats have traditionally supported unions which improve wages, benefits, and working conditions; the CFPB which returns money to defrauded consumers; higher taxes on the wealthy; broader access to health care; and other measures that seek to ease economic burdens and expand opportunity for the 90%. One can certainly argue that they don't go far enough. The ACA, for example, is a far cry from the universal health care we should have. Republicans, however, even before the Trump fiasco, have argued against all of these in the name of leaving everything to "free markets". As we see, when "free" means unregulated, the economic playing field tilts ever further from being level, shifting more wealth from the many into the hands of the few. That will now just accelerate.
To be clear, immigrants still break for Democrats on the whole. But the shift is strong away from them.
I'm in a weird position of trying to give voice to something I only have partial agreement with.
We had 4 years of Trump before. We pounded the fascism drum since at least 2015. I am there with you on that.
I have argued plenty against the neo-classical concensus on "free markets" and to be fair even the people I am trying to give voice to believe economic inequality is a problem.
But consider that Democrats are basically at an all time low and Trump is at a point he's comfortable with.
Perhaps, briefly consider that there may legitimate grievances in urban and rural centers.
The clubs of economic structural violence:
1) The biggest issue is that there are always plans for things that fall apart. There are so many things the Democrats are for, in name. But rarely do thins happen in reality these days.
There's pretty much always something like a 14 step, multi-year process where lobbyists and lawyers take a big chunk of money before anything is started, pushed forward, or completed.
This means when anyone is trying to solve a problem in material reality, not just "awareness," has to bring in people with money and capital just to get to the starting line.
2) Housing shortages - the worst in the most liberal states and cities. A lot of the zoning comes from historical redlining, many of which came in the tradition of Dixiecrats from before. Republicans also put more in. But Democrats have been in power in many of these places for a while, and instead of material making things better, they've been defending the red taped status quo. I can't believe a rational person can deny the existence of housing shortages where many of the majority of jobs are.
3) Rural broadband - $42 B in announced funds for it under Biden. How many people actually connected? Many say it's effectively 0.
I could go on, but I made the thread "Stop Criminalizing Upward Mobility" for more clubs of structural economic violence.
