What church or charity do you know of that will pay an individual's medical expenses? Same goes for their prescription medicine(s)? Sure, there are hospitals that will take on surgeries pro bono on a case-by-case basis, but those are few and so very far between. So, what you're suggesting, though noble, just isn't realistic.
Promote v. 1. To contribute to the progress, development, or growth of; further; encourage.
I can certainly see where the health care bill "contributes to the progress" of this country by "developing" healthier citizens, thereby advancing the "growth" of a nation. Makes perfectly good sense to me.
