I had to read that mess of a post twice to understand what you want...
Don't compare food to healthcare, food is food and healthcare is healthcare. They are distinctly different things, but I know i'm not going to be able to eat fabulous meals while my nieghbor is starving to death. First of all it would be impossible because before a human will starve to death they will kill for food and before they die from starvation they will even eat human corpses..It's history, it's common sense, it's obvious. So just like healthcare, we will never be able to deny people food. We only exsist on earth because we have taken care of eachother through millenia. How has sharing become a dirty word? How has helping others become and evil idea? How did they get you to think like that?
