We can't do it because there are too many people profiting off of the current system who don't want to give up so much as a dime of those profits. Now, don't get me wrong. I'm not against doctors making money. I just think it's possible to provide health care for everyone so that no one has to decide between feeding their kids and getting their kids the medicine they need, and still allow a decent profit for doctors. I just don't see why when it becomes a choice between profit and a patient's health, profit always seems to win.
