Yes it is, but it is a delivery issue, not a healthcare quality issue. We need to work on being able to get healthcare to everyone. Unfortunately, this is one of those things that the government absolutely cannot do at the same quality level as people buying their own healthcare. As soon as someone other than the recipient of the care starts paying for it, those providing it start NOT caring how much it costs, and do everything that they can to make it more expensive because they perceive a bottomless pit of money that is supposedly the government, and are going to ensure that they "get theirs." They also cease to seek ways to make it cheaper.
The solution to this is restore prosperity to the USA, and reject this "globalization" idea that has made the rich richer and the poor poorer, and get back to fair trade instead of free trade, and tariffs where appropriate. We ran the whole country on tariffs and excise taxes before the income tax was passed in 1913 (at the behest of the rich, of course, who were tired of paying almost 100% of the costs of running the country, since these were both consumption taxes and the rich were the only ones with significant money to be able to consume. America was hoodwinked into passing the 16th Amendment, and the income taxes have been dragging down the economy ever since. We need to abolish the income taxes, go back to a consumption tax as described by "The Fair Tax", and make the economy roar. Then everyone would have the money to buy their own healthcare, except for those comparative few (compared to the millions on welfare now) that would be left that still couldn't provide for themselves.
"It's like a C average student claiming: "I'm really a straight-A student! I got As in all the classes I didn't flunk. (And BTW, for some reason my education cost twice as much as that of any other student.)" "
I don't think that's a descriptive analogy for this case. I think the better analogy is that the schools in City X are capable of delivering the best education in the world, _if_ you can get into them and pay for all the class fees, but the fact that the residents can't all afford the class fees for chemistry, physics, or even the shop class means that a significant number of students graduate without the skills that are taught in these classes. Those less knowledgeable students are our "lower income" citizens that also don't get the best healthcare that America has to offer. It doesn't change that America has best healthcare on the planet, but the problem is that our AVERAGE healthcare outcomes are lower than the rest of the world because of those not receiving care, or receiving minimal care.
Lets abolish the income taxes, all of them, and make our economy roar, and this problem will become light-years easier to manage.
