This is from Robert Prechter's interview in the film:
Wal-Mart of all companies helps the little guy more than anybody. It’s the primary reason people who are blue collar workers at the lower end of the scale are surviving. It’s the primary reason people who are trying to survive on social security checks can actually do it. So it's the millions and millions of people at the lower end of the economic scale that Wal-Mart is helping. I think that contradiction goes to show that this (the protest) is mostly a sociological phenomenon and has very little to do with Wal-Mart’s activities.
