as opposed to the "workers control the means of production" idea of Marx, Lenin and such. You tax individuals and businesses and use those provide certain services. There's also the idea that you have legislation to protect workers (minimum wage, 40 hour week), consumers (air bags in cars) and the environment (no lead in gas.) Other than that you let capitalists do what they do best.

What I can't get is that so many people get so angry at the idea that poor people, or at least poor people younger than 65, could have access to health care in the US.

That's a pretty glib dismissal for real pain. Before Obamacare, in the nearest major city I could make an appointment with a gastroenterologist on a Thursday and see him on the following Tuesday. Now it is over six months for an appointment, and then for every subsequent appointment ... to see a nurse, not a doctor. There used to be five doctors in my rural county, now there are zero. While insurance premiums have skyrocketed. From my point of view healthcare has crumped. You then summarize my dismay as anger at the idea of poor people getting access to healthcare, like what else could it be other than class bigotry?

Just an addendum that most Nordic countries don't have that, those are set on collective agreements between employers and employees, typically through an union.
