What is a “right?”

I concur with Ann:

Isn't food important? Why not "universal food coverage"? If politicians and employers had guaranteed us "free" food 50 years ago, today Democrats would be wailing about the "food crisis" in America, and you'd be on the phone with your food care provider arguing about whether or not a Reuben sandwich with fries was covered under your plan.

But, in all seriousness, what separate healthcare from food? From oxygen?
