I hear little about how politicians (particularly the GOP) did absolutely nothing about fixing the system that, like most other things in the country these days, benefits the extremely rich at the expense of the poor.
1. The "very rich" don't have insurance because they use the world class doctors that don't accept it.
2. Poor people already had Medicaid. Why do you lefties always ignore this point? If you were poor or disabled, you ALREADY HAD government-provided health insurance.
3. The people who have signed up are not people who always wanted insurance but couldn't get it (see #2). The people who signed up are people who didn't want it in the first place but are now forced to get it.
4. "Fixing the system" means lowering costs, not shuffling around who pays for the higher costs (whether higher premiums, individual mandates, or taxation to fund a national system). Lower costs means tort reform, competition among providers, and giving individuals the ability to shop for care with price as a consideration.
The economics of a healthcare transaction are complicated and they're the reason costs are so high. When you go in for a checkup, you don't care how much the doctor charges because you're not paying for it anyways. The doctor just wants to get paid and the insurance company wants to pay as little as possible. The goals aren't aligned. If you were shopping based on price (by removing the insurance company from the picture), the doctor would have to shift his focus into providing the best service at the best rates because he's going to lose business if he doesn't. The insurance model is based on flawed incentives.
EDIT: You're providing valuable insight into the mind of the rank-and-file Democrat base. I always wonder what percentage of progressives are "in on it" when it comes to making up these lies and how many of them just fall for it. People like Obama and Professor Gruber know that Obamacare, environmental regulations, and amnesty are all about control, but they trick you "true believers" into thinking you're supporting access to healthcare, prevention of global warming, and social justice.
