Sarbanes still supports his Act (though he's no longer a Senator):
I decided to ask one of the bill's authors, Senator Paul Sarbanes, what he thought about the criticism. "These people have already forgotten what happened at Enron and WorldCom," he told me. "People lost all their pensions and retirement savings. The bill is really about ensuring that public companies have a legitimate system of internal financial controls. To me that is a worthwhile cost."
