This number is actually completely and utterly wrong.
The majority of the people in the OWS movement are where they are by choice.
You don't see the disabled veteran there, the person who lost a leg in a work related accident. Those people are working, earning a living, they have the right attitude.
We have a massive problem, and that's government control over everything.
Government handouts to moochers and looters like those in the OWS movement are now higher than government income, and will be higher than GDP in a few years.
Those people demand they be given widescreen plasma televisions, 4G cellphones, designer clothes, steak dinners, and brand new cars every few months, without ever doing anything whatsoever to earn them.
They're the professional unemployed and unemployable, buffed up with unionised government workers who would be unemployed and unemployable if they didn't have a government job where they could laze the day away in some cubbyhole without ever doing any work whatsoever (and yes, I know more than a few of them).
They fear their days of unbridled and unrestricted looting of the productive part of the population are under threat, and are trying to make the most of their situation while they still can, dragging everyone else into utter poverty to sate their unsatiable lust for stuff.
