<<He's not splitting up anything. I see no point in blaming him for what other people might choose. He's arguing people should be allowed to choose. >>
Well, he MUST be splitting up the risk pools if he is allowing people to choose. A choice implies at least two alternatives. So in his system, there will be at least risk pool A and risk pool B, both drawn from the potential risk pool of 300 million, and therefore each smaller than the maximum possible. Sorry, Prince, but on this one, you have no logical way out. By offering a system that fails to maximize the risk pool (single payer, universal coverage) the Grovemeister is necessarily splitting up the risk pool. And that was just theoretically speaking - - in real life, there'd be far more than just two choices.
Your real argument is that of two competing values (freedom of choice, optimum health-care coverage) you have sacrificed the latter to the former. You basically chose ideology over pragmatism. Which is a perfectly legitimate way of thinking, but we might as well be clear as to what it is.
<<I realize that is a radically bizarre concept. >>
Now, now. Be nice. Freedom of choice is neither radical nor bizarre, nor did I ever indicate that it was. Freedom of choice is fine in the supermarket. And in the spiritual world. And even in the political world, although I think the dictatorship of the proletariat through its vanguard the Communist Party would be preferable if the appropriate safeguards could be found against careerism, Caesarism, nepotism, and a few other isms could be found.
<<And I think by economical what you mean is removing the most responsibility from the individual by taking from other people, which frankly I find problematic on moral and ethical levels.>>
No actually I meant lowest cost/maximum benefit, bigger bang for the buck, best value, however that idea is expressed. Minimum waste reasonably achievable. This does remove some responsibility from the people, just as it's more cost-effective for people to pay a cardiac surgeon than to attempt to fix each other's cardiovascular systems at home. REAL responsibility would be exercised if the average voter recognized that maximising the risk pool and setting up a single payer would be his or her best health-care plan. The healthiest and the wealthiest might responsibly come to other conclusions, but they'd be outvoted by the average joes and janes.
