I think that if the health care system is viewed at all in a capitalist way, then there are competing priorities which make the system broke an unfeasible. The primary objective of our health care system should not be to make money, but to take care of our citizens. We need universal health care.
No, competing priority do not make market health care unfeasible in the United States, because competition still leads to efficiency. There will always be other people willing to enter the market and do a better job, regardless of whether a company acts in their own self-interests. If another stakeholder wants customer service, the other stakeholders will comply, in order to profit.
