Maybe that's because they don't have Supreme Courts who rule on their Commerce Clauses and keep them from doing this sort of thing and not calling it a tax? For whatever reason, they have this and we don't, and we can't have it under the CC, so sayeth the court. So it's got to be paid for as part of our tax liability, and if people are hunky-dory with that, we shouldn't have any problem!
Now we had a perfectly acceptable system in place to handle the needs of the poor, in state-operated health clinics. These were established years ago, to provide health care to those who were poor and couldn't afford it otherwise. Medicaid was also established, to help cover hospital costs of the poor. So, in a sense, we DID have universal health care.. it was available to everyone who qualified. And I would venture to say, the typical county or state health clinic, is up to par with ANY facility operated in one of your socialist Eurotrash examples.
What we have now, is universal INSURANCE coverage for health care! And it's MANDATED that we own this, by our government, as a condition of taxation for being Americans. When the premiums go through the roof, the people will scream in outrage... and guess what the federal government has been limited (by SCOTUS ruling) in its power to regulate because it's not an 'interstate commerce?' ...Ouch!
