I think that members of both groups have something at stake, but they're playing different "games": The Arab Spring was several tyrannies breaking out into freedom; OWS/99% is about economic injustice and structural political problems.

According to the Oracle at Wikipedia, both sides each suffered 50,000 deaths during the American Revolution. And 18th Century England was arguably more civilized than the Arab tyrannies that were overthrown this year. Something's right with the world when millions of people can achieve their freedom at a cost of a thousand casualties. I can't bring myself to say "only a thousand", but they paid a lighter toll than many have.

Political revolution is inherently violent, but issues like distribution of wealth and lines of power in a technically-free society don't have to lead to bloodshed. I think both groups are doing pretty well in their respective situations, to limit the violence on their respective scales.
