A lot of great points. Yes, insurance companies do compete price wise (especially in the individual marketplace), but you are correct, doctors and hospitals don't. This is where the increased cost issues are, in my opinion - nobody knows the price or shops for price.
In many cases, people can't really shop price in medical care, since smaller communities often have only one hospital.
And no hospital I know of, anywhere, has a price list you can see prior to treatment. Few physicians will reveal their prices in advance.
Comparison shop? Nonsense. These aren't grocery stores.
All for-profit insurers pay more for medical services than does Medicare. Insurance company premiums are controlled by State agencies, and they are allowed to charge premiums which provide them with a "reasonable" profit, calculated as a percentage of their total revenue. Thus insurance companies are motivated to prefer ever higher costs, which they then use as justification for higher premiums and profits.
So how do you shop price? Tell us how.
Of course you defend insurance companies. You're hardly unbiased, eh?
Medicare knows how to shop for price. They have enough insureds to say to most hospitals and physicians - "Take it or leave it."
Give Medicare another 200 million insureds and they can say that to all providers.
You'll need another job, Mags. One less salary for us to pay.
