I don’t know why this is the line in the sand. The American oligarchy has been running shit since Koch brothers o’clock. There are some small practical differences, but for all intents and purposes, those differences are negligable and the rich get the laws they pay the government officials to produce.
No power is ever as absolute as people think. AmeriKKKa has been in a death spiral for a while now, but it will probably still tske a really long time to disintigrate. If anything, fascism signals that the elite are losing their grip on power as it’s the tool they always turn to when desperately holding on. It will look like absolute power for a while, but it will ultimately burn itself on both ends until there isn’t anything left to burn. Alot of people will inevitable get burnt up between the flames though.
