remember that Wal-Mart is the largest company in the world! They are now also the largest grocery store in the world.
I worked as a PI in the 80's during the election for a group that suspected that the Unions in Chicago (sorry to be redundant!) were putting lots of cash into the Dukakis campaign. A group of us were sent to Chicago and "volunteered" at some of the campaign offices. We found what we were sent to find and the campaign was fined $350k by the FEC. While I was there I saw a memo that said that the goal of the Unions was to either "unionize Wal-Mart and Food Lion or to bankrupt them!" I paid close attention because at the time I owned stock in FL. At that time Wal-Mart ONLY employed close to 1m people and FL around 60
