You are making a fundamental mistake here. You are assuming that most people are going to end up with a better health care under 0bamacare than they had before.
That is patently false. There is no such thing as a great, regular, free lunch in perpetuity. Inevitably, 0bamacre will send health care levels in thic country into the pits, and make things much, much worse for the average American they they were before.
Heck the British have been up in arms against their screwed up socialized medicine for decades.
Most Americans are already against this 0bamacare abomination(by 2:1). Just wait till the taxes and the jailings in 0bamacare come into effect. The Democrats have signed their own death warrant.
No, just saying you can never get rid of entitlements. Once the government regularly gives someone something, they get addicted to it. They may demand more spending and taxes, they may demand someone else be cut. But they wont tolerate the government ending their benefits. In fact more and more will want to be included, like with SCHIP. People including Republicans prefer something that looks free.
Your example the British, you wont see them calling to end the system.
