Your right the health care system in the US isn't very good (I live in the US by the by). The doctors are more likely to throw some pills at you and get you out of there hair, there are two reasons for that:
1. I remember hearing a story on the news that if a doctor tells you to take or steers you to a certain drug for your illness the company that makes that medicine will pay the doctor. There more advertisers than doctors
2. Is that at least around the area where I live the hospitals and clinics are always full up. Its easier and may be safer for the doctor (mal-practice and all) to just throw some pills at someone.
Private Insurance is a huge rip-off, but you have to have something otherwise the hospital will turn you away. I've heard about people getting turned away more and more lately.
My Mother had to have her gall-bladder removed about two and a half years ago and when all was said and done the bill came to 20,000 dollar. That was just to remove something that's less than the size of an Ice Cube. She has insurance through the place she works and got lucky to the fact that she hadn't used it for anything major other than going to the clinic a couple of times so she only had to pay 200 bucks.
One of her co-workers has had to go to the hospital quite a bit though, and the insurance company just flat out said that this person was using it to much and wouldn't pay very much on any operations they needed do.
I tell you its a real same, that one of the most powerful countries in the world can't come up with something to help.
