On March 19, 2003, we were on the roof of the Zanon ceramic tile factory, filming an interview with Cepillo. He was showing us how the workers fended off eviction by armed police, defending their democratic workplace with slingshots and the little ceramic balls normally used to pound the Patagonian clay into raw material for tiles. His aim was impressive. It was the day the bombs started falling on Baghdad.

In order to compete in a corporations-dominated economy, worker cooperatives need millions of dollars to finance large-scale businesses in manufacturing and production.

"That's the hole in the cooperative movement which there needs to be some infrastructure for," said Michael Leung, of Somerville, MA, who last year earned a doctorate in Physics from Princeton University. "I don't personally see a way where co-ops have the mechanism for large-scale growth."
