Wal-Marts corporate success clearly depends on the success of their middle class customer base and employee's. Even if Democratic policies are great for Wal-Mart, policies that apparently bolster the strength of the middle and lower classes as the expense of the ruling classes will not likely win favor amoung a rather small, and affluent, group of corporate executives.

Walmart is where the lower class shops. The middle class has almost ceased to exist anymore. When other groups shop there it is mainly because, for vast swaths of goods, Walmart has chases the competition almost completely out of these sectors. However, when they want quality, they go elsewhere.

Subtract the top 25% of wage earners and the bottom 25% of wage earners and what you have left is the middle class. They're the ones buying all the flat screen TVs.
