The problem is this is all being treated as a problem with how you pay for healthcare rather than addressing the root problem, which is how to bring down the cost of healthcare to the point where the average person can pay for the bulk of their own healthcare out of pocket, just as they do for almost everything else in life. For those rare but very costly situations you have insurance, whose function is to protect against unexpected but otherwise financially damaging or ruinous events.
You carry automobile insurance to cover the risks associated with things like theft and accidents. You do not have automobile insurance to cover the normal costs of owning a vehicle, like gas and routine maintenance. The same is true for every other area of life for which you buy insurance--except healthcare. That is the root problem and until this is addressed there is no possible "cure" for the problem of ever-escalating healthcare costs.
I read that about 75% of healthcare costs go to treating chronic conditions. Chronic conditions aren't really a problem on a national scale until people hit their mid 40s. Then it is all downhill. It is really a question of who pays for healthcare as a person ages.
