"Wal-Mart is a low-wage firm and this indicates that it exploits its workers." Which of the following should cause one to question the validity of this statement?
1 the high profits of Wal-Mart
2 the large sales revenue of Wal-Mart
3 No one is required to work for Wal-Mart and, therefore, it must attract workers by paying them more attractive wages than they could earn elsewhere.
4 This is a trick question. Wal-Mart does exploit its workers and the below average wage of Wal-Mart employees illustrates this point.
