The reason they do so is that they're supremely envious of anyone who has a dollar more than they do. And of course many are simply misfits or unable to secure a decent job due to lack of intelligence or discipline. They're easily suckered by demogogues like Obama who tell them life isn't fair, they're victims of the rich, and he will make amends by extracting all that ill-gotten wealth from the producers er excuse me "greedy rich."
The great irony is: after power-hungry autocrats like Obama get done with all their programs, the rich are still rich, and the envious, feckless Dem faithful are still poor or poorer than before the Dem Supreme Leader i.e. King Barack etal started their wealth-destroying initiatives. They never learn.
that’s demAgogue...not demogogue.
