I could be wrong, but it seems like people who support a fully open deregulated market/minimal tax/privatized world have the following view:
the most effective engine for managing any resource is the unfettered marketplace. kill or be killed. if you help your neighbor, the end goal isn't to actually help him, but to better your own position in the end. empathy is just a tool for use in the same end game: bettering your own position.
I totally appreciate this point of view...it is just stone cold realism. It is social Darwinism and evolution of the human animal. Anything else is just cancer.
Its funny to see the ant used as a parable in this thread. Ants are proof that communism is an effective evolutionary force. After all, they survive by working together. And I'm pretty sure they have death panels.
