Its pretty easy to say they accomplished nothing, because its just stating facts. Day after day, the idiocy coming out of those Occupy camps discredited themselves better than any outside source could have. Plus, you speak of them going "global". Perhaps because the movement originated in Canada from a pro-socialist organization? It was never a spontaneous, organic movement. That is why it failed. You can achieve critical mass with the lunatic fringe, college professors and idealistic college students, but that is not a sustainable movement. it was a flash in the pan, aided by a media desperate to counter the Tea Party, but it ultimately failed. You need only look at the opinion polls on the "movement" to see the American public does not support it.
