Look, I'm not saying I agree, and I'd turn pretty much all companies into worker cooperatives tomorrow if I could, but the reality is the median American disposable income is ridiculously high compared to most countries (if I recall right, only Luxembourg compares, which, I mean...). Inequality is also ridiculous, and there are also a lot more in extreme poverty, but they tend not to be as politically active (because being in poverty is fucking exhausting, been there). But the middle class, which tends to be more politically active, still has way, way more wiggle room than the middle class in most other places. It takes a lot more economic pressure to pinch them hard enough to take action.
The fact is if you're poor, the US is financially an awful place to be while (most of) Europe is pretty tolerable, but a middle class American generally has way more money in their pocket (even accounting for things like health care) than nearly any other country's middle class. There's a reason a lot of young professionals from Europe go to America for 5 years or so to build up a nest egg to bring back to Europe... salaries for the same positions are usually way lower here and advancement is usually harder compared to the US (again, talking about professional work here). My wife is in middle management and can literally make about 4-5x what she makes in our country in the US... while things like rent and healthcare would take a larger % of our income, our total dollars saved at the end of the year would be way, way higher in the US (we've both lived and worked in the US in the past).
None of this should be read as an endorsement of the US system, I'm personally a socialist that would see worker co-ops required by law, and as someone who has moved from real poverty into the middle class, I'd gladly take a reduction in income to ensure my neighbors aren't on the street trying to find enough to eat, I don't believe in shutting the door after yourself... but it does explain why there isn't as much clamor to change it as people might expect. The unpopular truth here is we're a very biased sample here and the wider middle class in the US is actually doing pretty well globally. People don't like it, but it usually takes real economic pressure to get people into the streets.
