Actually I am a citizen I was born here thank you. But Wal-Mart does pay below standard wages. Also uses illegal tactics to keep the union out of their company.
Wal-Mart is the least of our labor problems in this coutry. Unions are mostly a mob driven scam and have always been. The "American thing" which you so proudly mentioned has nothing to do with fairness and equality.
The "American thing" is to make as much money as possible in as little time as possible by ANY means neccesary. (and it is not just American)
