I heard a guy on the radio who brought up a semi-valid point as to what he was protesting.

His point went somewhere along these lines: an average voting citizen has the power to vote for his causes and representatives every year or two. In doing so, he exerts some minute faction of influence over the direction of government when compared to a corporate or special interest entity, which can lobby, donate, bribe, or otherwise exert their interests 365 days a year, and with means of persuasion that are far beyond the capabilities of a normal citizen.

So there's the first valid point I've heard anyone make so far. I'm not sure "wall street" is the best target if you're aiming at lobbyists.
