The problem isn't trying to change psuedo corporatist-facist charade going on, it's that the purposed solutions to it (the OWS demands) simply further entrench said farce. How do they think Wallstreet got so powerful in the first place? Layers of regulations required to be in compliance with and a convoluted and confusing tax code essentially gave big brokerage firms, financial services institutions and banks a monopoly. They have the economies of scale to maintain compliance and smaller institutions simply cannot stay in compliance economically.
Let's take out the big guys, I agree, or at least force them to play on a level field. Imposing more controls just tilts the field further in their direction, or against the little guys who could give them competition, as it were.
