My reasoning is that the movement has popped up in multiple cities world-wide, and when you add up the numbers involved, the total is quite impressive (in the hundreds of thousands of people). This suggsts that the movement resonates.

Critics say it's not clear what they want, but I think a few clear points are being made, and they're good ones.

(1) OWL is high-lighting the fact that a high percentage of wealth is controlled by a tiny minority - 1%, and this gap has widened in recent decades.

(2) OWL is also pointing out the huge government bail-outs (in the billions of dollars) given to bankers in the UK and US, where everyone else there has to pay for the serious mistakes made by a minority of traders and real-estate speculators.

Yes, eventually they may have to move off the public spaces, but there's no reason why they can't set up camp in other areas where they have permission or have paid for -private camping grounds for instance.

Hacker groups such as anon have backed them as well you know. And they have those wicked-looking V-for-Vendatta face masks. Personally, I think a world-wide movement with permanant camps high-lighting various issues is kinda cool.
