My perspective is that a scale has tipped, a critical mass of people decided they want this sort of thing, and they got it. It wasn't rigged, it wasn't fraudulent, it was a democratic election. Critique democracy itself, or the criticism is incoherent. Make an argument for why a government should be disallowed from doing things that the voters want it to do.

They'd have to change the fundamental nature of business. Most US companies are run like tiny little fascist dictatorships, which is a great training ground for the real thing. The relationship between capital (owners/management) and labor is usually adversarial with "at-will" employment. Contrast in Norway, where businesses operate within a 3-way Agreement (Trepartssamarbeidet) - a formal cooperation between the government, employers' associations, and trade unions.
Americans would have to change capitalism too. The most reliable way to prevent the rise of the far right is to implement robust safety nets and low inequality, to reduce status anxiety and grievance.
But even in this thread they don't want to do that.
