We obviously don't
accept it, people have been trying to change it and it's been a major election issue for several years now. There's just a lot wrong about health care, so there are lots of facets for people to latch onto and say, "We have to fix this part!", and then the people who want to fix another part spend a few years bickering about which part is the key to fixing the whole thing (no part individually, but don't tell people that).
Also, people do not evaluate things independently and rely on pundits like Glenn Beck or Rachel Maddow to evaluate the situation and give them an opinion. Glenn Beck and the rest of the Fox News/right-side cadre tell everyone that health care reform is socialism, our system is the greatest in the world already, the government can't do anything right, and we'll all be turned into savages because socialism will steal our morals and make our children sniveling, awful thieves and layabouts. This is Glenn Beck's position mainly because the President is currently a Democrat. Maddow says the opposite of course.
Media in the US works by validating the opinion of your target audience, and doing this in an emotionally gratifying way that sounds like you are being logical and reasonable, and gives people little soundbites they can use to justify their position. People listen to Beck, Hannity, et al because they enjoy the emotional experience that it induces -- they like the righteous anger and validation of their beliefs, they are gratified by blaming all of the problems on the people that have an opposing viewpoint. They enjoy hearing little snippets that can be used to justify their (adopted) political positions in a sentence to a friend or colleague. It's just easier this way, and doesn't require any intellectual effort.
In short, it's all about flattery. People give you money, influence, and power when you spend all day flattering them, irrespective of its basis in reality.
There's a lot of misinformation out there.
The majority of Americans also have passable health coverage, so since it doesn't affect them, the people that are not politically inclined are not particularly interested in the debate and they don't understand the difficulty for people that aren't happy to be bound to BigCo forever.
