What you're failing to consider is that the Scandinavian countries are already a lot more equal that you guys in America, so those taxes are not as scary as they would be if you just transplanted them into the United States. I don't believe that Sanders, if President, will fight for taxes that are appropriate for a highly equal country - that will only raise the burden on the middle class. If you listen to what he has to say, and not just Fox News, then you'd know that he wants to tax the 1%, those people who aren't representative of the middle class, and are take home a disproportionate amount of income and wealth.
Uh, sure Canada has it's long wait times - you've been up here yourself and found out, yes?
Look, my provincial program covers medically necessary emergency and preventative care. That means if I go to the doctor, that's covered. If I fall ill and have to stay at a hospital, that's covered. If I get cancer and have to get surgery and take medication, that's covered (usually). None of that comes out of pocket. Drugs can be partially covered, but our prices aren't as ridiculous anyways. I don't know about you, but that's a lot of security that we're buying with our money, and we don't even spend as much money per capita than Americans do on healthcare, so there's that too.
The United States needs to ask itself two questions. Do you want a highly educated workforce that's competitive with those of other Western countries around the world? And if the answer to that is yes, then are you willing make that happen as a society?
If the government does not step up, you're going to have the same old status quo - hard working, smart kids will not be able to enjoy the fruits of a university education because they cannot pay for it, not because they are not deserving. Compared to many other Western countries, the cost of college is out of control.
Free college is honestly not the most important point to people who care about this issue. The point is to make college more accessible. Personally, I'll be happy with any program that can drive out-of-pocket tuition costs down at least 25% (somewhat less vomit-inducing for this Canadian here), but I can't really talk about what an average American is willing to stomach for affordable post-secondary education.
