If Pigs Are So Damn Smart...

Goldblog reader Erik Ruda writes, in reference to the pigs vs. dogs debate:

If pigs are so smart and dogs are so dumb, how were dogs able to finagle themselves into a position where humans (the supposed smartest ones) pay for their food, grooming, and yoga (doga) while pigs find themselves prisoners on factory farms awaiting their death?

This is a corollary to the as yet unassailable argument, "If Thomas Edison was so smart, how come he's dead?"
