I guess this is the problem with any protest movement - you have no top-down control, and so any good messages can get lost in the noise. I think the occupy 'brand' is pretty much damaged beyond repair for now, but if the core of the people believes what you say, then it's possible to create a new organisation and leverage from occupy before it's forgotten. But a new organisation would have to be top-down and control the message to get the point across.
For my part, I agree with the points about regulatory capture and corporatism. Large businesses pretend to like capitalism, but in reality, they get terrified of smaller startup companies stealing their lunch money and rendering them irrelevant in a decade or less.
Too big to fail is indeed too big to exist. The role of governments must be to prevent monopolies from forming, not to legislate them into existence.
