The VA health system is a single payer system run by the government. I don't see where that has worked well.
My view is that we allow (force) a competitive system where any insurance firm that wants to continue to do business must offer group plans and only group plans where they can only ask thing like do you smoke, drink alcohol or do drugs and number of adults and children covered, maybe, male or female. No age, medication or present health concerns type questions. They cannot offer any other special type plans that would siphon off the low risk customers. (Employer based systems are already group type plans but similar info restrictions should apply to them as well.) They can offer different options that may affect pricing such as different co-pays, deductibles, no pregnancy benefits and the like. That way anyone who wishes obtain health coverage can do so at the best coverage for them per dollar the same way competition gives us the best meal per dollar whether your preference is hamburgers or steaks. If you can't afford steak, at least you can afford to eat. If you don't like the way the insurer is treating you, you should be able to easily move to another carrier. For those on the low end of the income ladder, some kind of government assistance that provides basic preventative and essential care is a must.
