How exactly do you propose to "remove profit from medicine?" If someone wants to have a procedure done and their insurance doesn't want to pay, they can still pay the doctor to get it done themselves. And it will still be very expensive because doctors in the US are used to charging very high salaries and using medical equipment and medicines that cost a lot of money. Insurance companies are required by law to use 80 percent of their income to pay claims out to their customers already. Medicine costs a lot.
