Well, they claim to be the 99% that the 1% have screwed over. They are all walking around with signs saying "We are the 99%" while chanting the same thing. They also chant "Banks got bailed out, we got sold out"
The CBOT, or tenants in thier building have twice countered thier "We are the 99%" protest chant with a "we are the 1%", in the form of signs in the window, or printing flyers and throwing them out the windows onto the protesters below; which I think is infinitely hysterical.
