I had thought it would fizzle out. It hasn't. It's getting bigger, it's getting more coherent, and it's finding a winning narrative with this "we are the 99%" line.
Mainstream media ignore it at their peril. This could be bigger than the tea party.
Edit: People keep asking "what do they want?"
Isn't it obvious? They want want Lincoln talked about: they want "government of the people, by the people, for the people". They know that isn't the case. Not all of them can articulate it, but they all know somewhere that the American government—and, in fact, pretty much all modern governments—act at the behest of corporations. These corporations are given the same rights as actual citizens, and carry outsized weight due to their enormous economic power...and as they are generally owned by a tiny minority of people, they provide an outsized voice to that tiny minority.
That's why there's all this talk about the "99%" and the "1%". The 99% have no real voice. The only voices that are listened to are those of the corps, and the corps are overwhelmingly owned by that tiny minority. Even if members that tiny minority wanted to help the rest, they can't, because the corporations that act on their behalf are (somehow) legally obligated to fight anything and anybody that threatens the income of that minority.
(That's what corporations are for, after all. They make money. That's it.)
People get that this situation cannot continue. They get that this isn't working properly. They aren't yet quite sure why, or how to get out of it, but they KNOW that things are broken. They're looking for someone to fix it. If someone doesn't, they'll do it themselves.
Re-Edit: The truly bizarre part is that even people on Wall Street know that the current system is broken. They don't like being blamed, true, but they know the problem. The issue is that the people with actual power and influence won't believe it for ideological reasons.
