The problem with Obama's health care reform is that the GOP is over-run with Randian Objectivists, Evangelical Capitalists, and McCarthy-style Communiophobes.
The Randians object because in their ethos, if you can't provide it for yourself you don't deserve to have it, so those who can not secure access to health care entirely on their own do not deserve to have any health care. "Are there no workhouses? No prisons?" The Randians think it is right and just for this "surplus population" to die from lack of health care.
The Evangelical Capitalists are so committed to the "pull yourself up by your own bootstraps / God helps those who help themselves" meme that they can't see past it to realize that this ethos screws you entirely if you HAVE no bootstraps to pull up, if the bootstraps were taken by a predatory bank, or if you are stuck in a desperation subsistence job that doesn't pay enough to even take the bus down to the bootstrap store to window shop. Oh, and that God has never been proven to directly help anyone get health care. These people are downright offended by the idea of Obamacare because they believe their patented Capitalist Jesus would hate it. Which is weird, because the Jesus of the Bible personally provided free health care to every single person who asked him for it whether they deserved it or not.
The McCarthyists? Well, they are so terrified of anything that can be even remotely described as "socialist" that they have fainting attacks at the mere word. (Nevermind that the Soviet Union is long gone, and was never "socialist" to begin with. Hell, during the Soviet era, with our food stamps, housing assistance, and Social Security, the USA was more socialist than the Soviets were.) They don't really know what Obamacare even is because at the first mention of it they clamp their hands over their ears and scream "LA LA LA LA LA I CAN'T HEAR YOU LA LA LA LA!"
But I think in the end they are all really just Randian Objectivists, and are so deeply resentful of being asked to help others. They just don't give a shit if their neighbor dies of cancer or pneumonia as long as they get $20 more in their paychecks to spend on porn and Bibles.
