No, I don't. We resort to protest too often and too quickly in this country, so much so that we sometimes protest for the sake of protesting. Those people who camped out in parks should have organized politically instead, by starting their own political party, or exerting influence on an existing political party. They could have pressured government to hold the large investment banks accountable for their part in tanking the economy. They could have pushed for legislation to make sure that there would be no more bank bailouts, or if there were, that those who ran those banks so poorly would lose all their personal profit as part of the bailout plan.
If they absolutely had to protest, they could have done it more effectively by transferring any money and/or credit card debt they themselves had with the big banks to small local banks and credit unions, and they could have encouraged other people to do the same. If you want to get a banker's attention, you do it by taking money away from him, not by camping out in a park.
