Government can pay more because it has the power to take money from those to whom it rightfully belongs without giving them a choice.
This is just silliness. How much money would you make in a world without roads, electrical grids, police, firemen, armies to protect borders, people to inspect food, water, and goods, a court system to enforce your rights...etc.?
Nonsensical glibertarianism. This is a democracy, "The Government" is us. We got together and decided these are the things we should collectively provide. If you think it sucks, start a movement to change things. If it's popular, that will be the new government.
Not so scary.
A private company has to obtain money by selling goods and/or services that consumers will buy of their own free choice.
I love this canard. Show me the "choice" in the healthcare industry. The vast majority of people who are able to obtain coverage do so through their employer. They rarely have much choice in that situation. Most states only have three or four insurers that provide coverage.
But to the broader point, profit-motive can be a powerful force, but it can also be damaging. Profit motive drives people to develop clever ways to generate that surplus. When we're discussing Apple or Google or biotechs or care companies, this is a very good thing. It generates innovation, has a general effect of driving down prices and creating efficiency, and spurs creativity. Of course, it has to be regulated lest we arrive at "economic breaches" (cheaper to settle lawsuits from wrongful deaths than build safe cars, for example).
But what good is profit motive in private health insurance? What innovations does that incentive generate? I'd be curious to hear the free market advocates explain what the benefit of that is.
We know it hasn't created efficiency, which is why Medicare has such intensely lower administrative costs, and the only innovation in the market is to develop new ways to deny people the coverage they're paying for. The only way to increase profit is to take in more and pay out less. That does not benefit individuals or the nation as a whole.
I would challenge any free market advocate to explain why profit motive is at all a good thing for the health insurance industry without reference to vague, inchoate "principles."
