Can anyone succinctly explain the benefits of having a market for private health insurance companies, rather than a single provider of health insurance (government, aka "public option")? Can a capitalist case be made for their existence? Does the lack of a large private insurance market in countries with government-provided health insurance cause lots of inefficiencies and waste?
The purpose of government is not to require the most efficient option. Government isn't capable of it anyway. Government is force - nothing more. The purpose of government is to protect our rights. "Single payer" (a euphemism for socialized medicine) by definition violates rights by forcing people to do things against their will. For example, in Canada (until recently) people were prohibited from using private health…
Also, here in Connecticut (the place where the rich historically sent their kids to school), there are plenty of public schools that are at least as good or better than at least some nearby private schools. When you get into preschool, for instance, the public schools are a HUGE improvement over all but the top-tier private ones. Likewise, the "magnet" program schools are a public option that is as good or better than most private schools nearby (they are special, well-funded by the state, and use a lottery to get in, though).
This is coming from someone who agrees with you in principle, too. Reality is nuanced, though.
