Trying To Solve A Puzzle

I'm puzzled by something. One of the reasons that GOPers are supposedly against the public option for medical insurance -- where the government is involved in funding a Medicare-type system for the rest of us not on Medicare -- is that it will harm private insurance companies and drive them out of business. But isn't this how capitalism is supposed to work? If the private insurance companies are doing such a damn good job, then they shouldn't have to worry about losing customers. If they're losing customers, then shouldn't they adjust what they're doing to satisfy the needs of their customers.

And another thing that puzzles me is this. I keep hearing that I don't want the government involved in deciding what kind of medical care that I can get -- don't want the bureaucrat making the decision of the doctor. Well I don't know about you, but this happens to me already. I, or my doctor, often have to contact my insurance company for approval for certain treatments -- my brother deals with this all of the time as his insurance company continues to insist that my niece's Autism is not a medical problem and is thus not covered by his insurance.

And once again, I just stick with my doctor told me: $10,000 a year in insurance costs for a relatively healthy person is wrong, especially since they're going to try and find a way to not pay for my treatment is something serious ends up being wrong with me.
