I think we disagree on this. I interpret the failure of OWS et al. as the inability of the protestors to take their ideas mainstream. While gerrymandering, voter targeting and propaganda via mass media do dilute the protesters' votes, change is clearly possible. We saw this with the Arab Spring where the protesters were up against a much more authoritarian and anti-democratic state. If I had to guess, I'd say the problem facing the American left is complacency. A lot of people still think things are going reasonably well and simply do not empathize with the concerns of OWS or the sunrise movement or the BLM movement. It's hard to move the needle politically if a significant minority simply do not believe that there's a crisis worth reacting to.
