If you really belive that Walmart is the ideal example of American corperate enterprise, then I suggest you do a search on Google. Enter: lawsuits against Walmart. If all Americans and American corperations practiced the same ethics that Walmart does, places like this board would not exist. Everyone would be selfish and no one would share. Walmart is the poster boy for corperate greed.
While some of your points are valid, comparing employment at Walmart to working in a sweatshop in some 3rd world country is off. There is something wrong about a multi-billion dollar corperation trying to force their employees to work off the clock. I won't go into the worker conditions at the foreign manufacturing plants that turn out Walmart goods. When other corperations can obey the law, treat their employees fairly and turn a profit, its not unreasonable to expect Walmart to do the same.
