I did not say, nor do I think, that capitalism is "the least worst system". I'm sure we could do better in many regards, but that's quite irrelevant to the point anyway.

America's version of capitalism isn't the only cannon version of capitalism (and I could write a whole-ass essay about how the current state of affairs in the US goes back decades, and is fundamentally unfixable due to the federal nature of the country with its urban/rural divide mixed in with Electoral College and FPTP voting essentially preventing any meaningful structural reform).

There's no need to dismiss neoliberal social-democracy, just because it's "different" from the mess that America got itself into. Europe's achievements stand on their own, and America's systemic failures being blamed on "muh capitalism" completely misses the point, and the actual root cause of the democratic back-sliding which is corrupting the system in favor of the elites.
