One of the problems with medicare is that the filthy rich are just as eligible as the filthy poor. I don't believe that people with huge incomes should be eligible for medicare and those freaking scooter chairs cost way to much.
Many prices in health care are artificaly cost inflated. Look what hospitals charge for an aspirin.
I remember when doctors made house calls and people did not even need health insurance because the prices were affordable. What went wrong? Pure and simple greed in most cases.
