This era is a lesson in the nature of power and what people will do to get it. The lesson is: liberal democracy must be continuously defended with positive action.

In the US, both political parties work for Capital, not the workers and do not provide positive action. This leaves an opportunity for fascists to be elected to power by campaigning on solving the problems that arise from unregulated capitalism. What else are voters going to do? Keep voting the a political system that does nothing for them materially? The counter is a government that delivers for citizens. That means: low food and energy prices, healthcare, job security and worker protections, housing affordability, etc. (And I don't want to hear any quibbling cop outs from liberals or centrists or the vote blue crowd about how Kamala was the only sane choice who promised to keep GDP growth above 5% or cancel some modicum of means-tested student loan debt etc.)

So, that's how you get concentration camps after once liberating them.
