"Something like 70% of Americans want universal healthcare"
Maybe that used to be a correct statistic, but from the polls I've seen, a majority are against the proposal as it stands. Maybe they realized that they don't want it when it actually costs something...
"If America is going to be able to afford universal health care it's going to have to cut back spending and/or raise taxes"
Chrisp, Chrisp, Chrisp. You're forgetting modern economic theory. Paying for things doesn't matter - we'll just go deeper into debt. And the national debt doesn't matter at all...
Seriously though, morally, I think national health care is, simply put, evil. But I'm an objectivist, and I've tried debating the finer points of Objectivism, and it's, frankly, an argument I'm tired of having. Especially on the internet. So I'll attempt to display why, practically, national health care, and socialistic principles in general, simply don't work.
Point One: From a microeconomic perspective, the government subsidizing an industry such as healthcare (Or education anyone?) creates, essentially, an illegal monopoly. They can provide for free what other organizations, ie. private healthcare providers, must provide at a cost. In order to remain competitive, the natural response (As has been the case in education) is provide a high-quality high-cost product to the very rich. The niche market of catering to the lower and middle classes would even less appealing than it is now, with the result being that the lower and middle classes have no choice but the government system. If you really think, after looking at the public education system, that modeling our health care system after the same model is a good idea, well, I don't know what to say. As someone who lives in Tennessee (49th in the nation in education) and went through (the best) public schooling (in the state) let me say, you DON'T want that happening...
Point Two: Since the healthcare system is relatively monopolistic, a direct subsidy wouldn't work. In monopolistic or oligopolistic industries, the subsidies tend to go simply to the profits of the companies, because they will raise the price by the amount subsidized. (This would be for a pure monopoly, of course, or a perfectly colluding oligopoly, but you get the point - the subsidy would be passed mostly to the companies, not the people.)
Point Three: As Chrisp said, we have to pay for this some way. There are essentially three options: Raise Taxes, Cut Spending, or Borrow Money. Raising Taxes, obviously, is a pretty bad idea in a recession. I don't think that anyone would argue that. Cutting spending I would be relatively neutral towards. Taking money from one useless, corrupt, and evil program and giving it to another useless, corrupt, and evil program, I don't really care about. But it would never practically happen. This leaves us option three, which is borrow/print more money - the far most likely option, in my opinion. This only adds to the $66 trillion in unfunded liabilities that the government currently has. Guess who gets to pay that debt folks? That's right, my generation! Thanks Mom and Dad!
The bottom line is this: When we have a bill of $66 trillion (That figure is probably outdated - it's probably higher now) that is going to come due over the next 40 years, we don't need to be adding government programs. We need to end almost all of them if we want any hope of surviving as a nation.
All of this being said, on a practical note, I'm all in favor of national health care. There's no way that we will actually be able to cut spending to a level that is remotely sustainable, meaning that at some point in my lifetime, America will collapse due to fiscal irresponsibility. Just like the Romans, so too will the America fall. And I'd just as soon that come sooner rather than later, so I'm around to help pick up the pieces.
The attribution of the following quotation is ambiguous, but it is largely attributed to Alexander Tytler, and is quite appropriate to our discussion:
"A democracy cannot exist as a permanent form of government. It can only exist until the voters discover that they can vote themselves largesse from the public treasury. From that moment on, the majority always votes for the candidates promising the most benefits from the public treasury with the result that a democracy always collapses over loose fiscal policy, always followed by a dictatorship. The average age of the world's greatest civilizations has been 200 years.
Great nations rise and fall. The people go from bondage to spiritual truth, to great courage, from courage to liberty, from liberty to abundance, from abundance to selfishness, from selfishness to complacency, from complacency to apathy, from apathy to dependence, from dependence back again to bondage."
