The protesters have sent out requests (pleas?) for everything from poster printing to medical assistance to sleeping bags to caterers. I find it fascinating that the people who would provide such goods and services are the very capitalists that the 'occupants' are protesting against. To move beyond the first round volley of discussion on that idea, yes, I will concede that the donations will likely not come directly from the capitalists, but from donors who purchased the goods and services from the capitalists.
So um what? The same goods could be produced by worker cooperatives if the world was so organized. Google Mondragoon and tell me they couldn't. So like I said, so what, if they happen to be produced by capitalist at present.
