This revolutionary, anarchistic, borderline destructive movement globally has not been working out so well. The countries that have tried it recently are showing that they are much worse off now. Perhaps 20-30 years from now things will have stabilized and become a utopia, or more likely they will follow the traditional course after a revolution, which is the new regime becomes as corrupt as the old.
As for # 4, I wholeheartedly agree.
And to be clear, I have no grievance with the protest on a whole, I just find it to be ineffectual and potentially more harm than good. I want the issues resolved as much as anyone, I just disagree with this course of action. I am however moved by your passion.
I'm not sure what you're referring to with "borderling destructive movement globally". If you're referring to countries that have had violent revolutions or other sudden regime changes, then I don't think that's the ultimate goal of the Occupy movement here in America.
The way I see it, there's a growing number of people who see our problems as institutional in nature, and that superficial reforms are not good enough. Individuals vary wildly among the actual population of the movement, but I think the general motion is towards a cultural revolution more than a legislative or regime change revolution. People are getting together, conductive social experiments, challenging world views, and having serious discussion about different ways of life.
One aspect of this is what you're saying about the middle class and their ability to work. Yeah, the individual benefits from being able to work in the short term. However, no business pays an employee the full value of their labor. If they did they would, by definition, not make any profit. Employees are paid to generate profit for the business, and that profit is distributed among shareholders and executives, not employees. This is the driving force behind consolidation of wealth, which causes economic hardship and severe disparity in the long term. This is but one gear of the machine that needs to be stopped, and the working class will continue to contribute to their own dilemmas until that happens. Profit as the underlying motivation for most participation in society is something that more and more people are realizing must be done away with, and that is a kind of change that can only happen culturally through widespread, sincere awareness and discourse.
Similarly, it's rather narrow-sighted to believe that the Civil Rights movement's victories were strictly legal in nature.
