@snood,
Not significantly, but let's say a lot more people are aware of income disparity.
I suppose that's an achievment in the sense that educating the public about anything is an achievement, but it didn't take 40 days or living in parks and marching in the streets, and they're not going to reach a whole lot more Americans by camping and marching for another 40 days.
You and others can be either impressed or content with the outcome thus far from OWS, but I think its meager, and it certainly won't be worth the violence that will, I feel certain, arise if they continue in the current manner of the movement.
Whether the violence stems from poorly trained or simply vicious police or from protesters who are bored or want to generate Youtube videos, it is predictable, and therefore can be avoided.
