Unbelievable.
Hey wait a minute here...
Do we really want the government in our lives this way? Now they are the nanny who has to tell us over and over again that we need to eat right and move around? I don't think that is their responsibility, is it?
I want my health plan to cover my docs and my meds. I'd like it if it (or my company) would help with my gym membership--or at least let me use my FSA/HSA to pay for it. But I don't need them telling me that I shouldn't get fat--especially after they deduct part of my pay check.
Given that the "we bear the costs of your behavior, so we have the right to regulate it" argument has brought us compulsory seat-belt and helmet laws, it's not a stretch to imagine that there are those who would seek to use the same argument to grant the government the right to do the very things that you mention. Whether the government would actually do so is an open question, and it would be interesting to learn more about how other countries have managed to reconcile the imperative to cut costs with the necessity of maintaining personal freedoms that might be curtailed or regulated by the state - from what you eat to what you weigh.
I'd have no problem with a private company rewarding healthy behaviors with lower premiums, and punishing unhealthy ones with higher rates, but placing a coercive power of this magnitude in the hands of the state seems fraught with quite a few more risks.
Do those other countries with health care have as many lardasses as we do?
