So what's the limit? If you permit what the market will bear the market will charge the sick and injured all that they have as they have not much in the way of choice....unless choosing death is a considered a reasonable choice.
I'll challenge you here. Name one other industrialized nation, besides the U.S. that permits health care insurance companies to operate as "for profit" businesses? Name one other industrialized nation that hasn't implemented health care cost controls?
Have you been paying attention lately where hedge fund managers in the U.S. are buying old drug patents for low cost live saving drugs and then marking them up by a thousand percent or more? It's not like they are trying to recoup R&D costs. They are essentially charging the highest possible price to achieve the highest possible returns because the people who need those live saving drugs have no choice but to pay that price as these bastards hold a monopoly on those drugs. How is this "free market"? How is this in the least possible way either ethical or moral?
These cost controls are needed because without them they drive up health care costs to ridiculous levels and people, who would like to live, have no choice but to pay them. That isn't "free market". This is monopoly capitalism.
