I've said--I have to say that there are arguments to be made for both these approaches. But either one would represent a radical shift that would disrupt the health care most people currently have. Since health care represents one-sixth of our economy, I believe it makes more sense to build on what works and fix what doesn't, rather than try to build an entirely new system from scratch. And that is precisely what those of you in Congress have tried to do over the several--past several months.
