stores throughout the country. they don't have enough in common to sustain a class. the women say they do. there was that common policy at wal-mart's executive that allowed gender stereotyping to seep into the management of the store where is local managers made all the decisions about who got raises and who got promoted. what is to become of class actions here? womens group says if you can't have class action, you lose the most potent tool to sue for discrimination. if all you do is say a company did something wrong, you never get enough lawyers to take the cases as a class action where you can sue for back pay and money damages. a lot of corporations say the class actions have become abusive. including g.e. the part owner of universal. they urged the supreme court to rule for wal-mart. >> pete williams, thanks very much. speaking of the supreme court.
