Yes.

> The argument is that democracy ALWAYS leads to tyranny and collapse.

Rather than Plato's mob rule criticism, I'm using the more contemporary capitalism-vs-democracy (winner-takes-all) food fight.

The tension in USA, at least, has always been wealth vs democracy. The "liberal" in the traditional "liberal democracy" was a reference to our economic system of free enterprise. The aspiration was to balance winner-takes-all with will-of-the-people. Basically the formulation of modern Nordic "democratic socialism".
