Rewind a bit over 100 years and the robber barons had an iron grip over the US economy, US politics, and people who understood the mechanisms despaired at ever prying it away from them.
Then the wind shifted and, suddenly, we could and we did. It took them decades to undo that progress and decades more to reassert their grip.
Don't self-sabotage by imagining that it is impossible to achieve change through democracy. We've done it before and we can do it again.
Can we though? There is marked difference in how the government reacts to populist demands. Notably, they learned from Vietnam how to manipulate the population to divide public opinion. I am not sure people today can overcome such organized machinations.
