Just because those at the poor uneducated end of the political spectrum can't articulate their position, doesn't mean they don't have one, and what they won't do to enforce it when their backs are up against the wall.
It seems technology and modern society has made it easier for them to organize and use that power, doesn't it? How prophetic Bradley Nowell was, emm? He knew what the streets were like, all they have to do is listen.
