That sounds like a bureaucrats definition of success. "It's not about accomplishing real work, it's about the process, getting involved in the process, etc. etc." Seeing how wall st. is at all time highs using printed money, and the largest mega banks are still mega, it's a bit optimistic to call OWS a success.
Don't get me wrong, I think it was a great effort... and I really like the 1%/99% coining... but perhaps it's time to look at reality.
1. re-igniting a national conversation about the nature of wealth and who has it and for what reasons.
2. Giving a large number of people who were isolated in their individual homes a space to come build some kind of community.
3. Several sub-organizations, such as Occupy Sandy and Strike Debt, have been incredibly successful in their niche.
4. A whole new generation of people were introduced into some aspect of activist culture.
Those are just some, off the top of my head.
