Spiders are one of natures most magnificent creations. They have 8 eyes and 8 legs and create webs that look beautiful and capture the imagination. Those webs - seductive as they are - are also deadly. Should an insect become ensnared, the spider immobilizes and enwraps the prey, then sucks all the life blood out, leaving behind an empty husk, discarded and forgotten.
It's an apt metaphor for the Ayn Rand inspired economic web woven by the free market scheisters who entice those at the bottom of the economic ladder to vote against their interests. They point to socialism as the demon, while these voters work for sustenance and watch their hard-earned dollars float up to those at the very top.
