From South Asia to the heartland of Europe and now even to Wall Street, these protesters share something else: wariness, even contempt, toward traditional politicians and the democratic political process they preside over.

They are taking to the streets, in part, because they have little faith in the ballot box.

"Our parents are grateful because they're voting," said Marta Solanas, 27, referring to older Spaniards' decades spent under the Franco dictatorship. "We're the first generation to say that voting is worthless."
