Now, if you are complaining about the system, you are probably a well-educated and working individual with enough income that you actually do pay your medical bills. Unfortunately, the real people being screwed in this whole ordeal are the working middle-class. American medical care is expensive (due to litigation, the price of malpractice insurance, expensive medications, research, etc.), and those working enough to pay their bills bear the brunt of the problem; however, you are still terribly naive to think socialized medicine is the answer. Before you cry any longer about the system do this. Travel down to Latin America or another country with socialized medicine and try it out. Acquiring health care and treatment is quite different with such a system. You may soon change you mind and come to appreciate what you already have a bit more. Stop thinking you're politically informed and start thinking more realistic.
If you really want to make a change in the system, here is my advice. Advocate for caps on malpractice claims and consequences for inappropriate lawsuits. The price of physicians' malpractice insurance will decrease, the price of physician costs will decrease, and hospitals and doctors wouldn't have to charge so much for care. As for the extremely high cost for medications, we're all screwed.
Lastly, if you still want socialized health care that bad, leave.
