Rush Limbaugh feels that people on public assistance are worthless and should be left to struggle on their own. More often than not, there is a component of racism involved but the main jist of it is that the poor are barely human and not worth helping. Rush Limbaugh, a fount of human compassion if ever there was one, made the following comparison:
"The animals must learn to fend for themselves if they are to survive and thrive. When you feed animals, they become dependent and no longer function as nature intends."
His comparison exposed his support of governmentally monitored national containment zones (national parks) for the underprivileged (animals) replete with posted laws and directives (do not feed the bears) which would mandate that compassion and charity are against the law (if you feed them they will die).
He also exhibited his ease in dehumanizing those very people in society who he deems to be animalistic and primal.
Darwinism is a theory that in nature only the strong survive; Social Darwinism is a man-made construct of laws and regulations which are created, specifically, to deny the underprivileged access to resources.
