Yes.
I personally as an anarchist want to see efforts to reduce and eventually eliminate the power of capitalism, corporations, and markets. I want to replace them with alternative structures.
However, I would not support any movement whose logic was brutal or who ignored the rights of people today for a better society tomorrow.
But the Occupy movement should be one that even people who are far further to the center than me should support. Even a die-hard believer in capitalism should not accept our current highly corrupt, crony capitalism. We should have reforms that break up inequality caused by financial speculation, investor's rights treaties, and specific policies that create inequality.
