(*Because there's also such a thing as "Democratic Socialism", and, if anything, that's what Bernie and AOC call for, you know the likes of universal health care and affordable education and appropriately taxing billionaires, because those are obviously horrible things)
Universal Health Care is overhyped. It's built on the exploitation of the middle class, where some pay much more, but get the same ****** service and waiting times. The USA's problem is that both sides of the service - insurance, hospitals - is private. It needs reform, not making it worse so everyone can get it. The sector's profits should be regulated, and life-saving care provided for everyone, while the ones who finance the system don't get worse care than now.
Affordability of education depends on mostly on earning potential. The student loan debt originates from the same thing as the trade deficit and the current Trump presidency: when free trade agreements were made, the working theory was that while well paying manufacturing jobs will go overseas, even better paying white collar jobs will be created, so everyone should get a degree. Very few of those jobs materialised, what happened is the oversupply of graduates (in mostly useless fields) increased entry requirements for existing jobs, when people with high school diplomas retired, college graduates took their place, but for the same salary level, well, because the job stayed mostly the same. Democrats let the factories go overseas, urged everyone to go to college, get a useless degree while listening to Marxist professors, then promising them to save them from student debt, just vote for us.
Ask Norway how wealth taxing rich people works for them. There is a rather simple solution to get more tax from the rich without forcing startup owners to sell their company before it becomes viable based on paper valuation. Tax share buy-backs, and tax non-financial companies hoarding cash. They will be forced to either invest and grow the economy, which will create tax revenues indirectly, or forced to raise/start paying dividends to support their share price. That stops billionaires living on loans backed by equity.
But Bernie and AOC do not want solutions, they want simple catchphrases they can use in their campaigns again and again, doing as little about it as they can get away with it.
Take that from someone who actually COMES from a former actual Socialist country.
But since you're someone who, according to your avatar, considers taxes as theft, you don't understand much of what it means to be part of a society, and any further discussions are moot.
I'm old enough that I actually lived under communist rule. AOC and Bernie might not seem socialist based on their current agenda, but how they operate, the propaganda tools they use is very much of a socialist. Even my country's communists didn't start out with saying "we'll send the former nazi brigands now working for us to sweep the attic in villages", they started with talking about the aristocracy. I'll never trust anyone who's on the left, regardless of what they say at the moment. You can look back the democrats went farther and farther to the extremes as their agenda was met in social issues.
And yes, wealth taxation is theft.
