The conviction of former Enron CEOs Ken Lay and Jeff Skilling on May 25th made front-page news all around the world.

The Welches say, however, that society cant afford to allow a small group of companies led by Enron to rewrite reality and make businesspeople cover in shame and lose their courage. We need a return to the optimism, confidence, and risk-taking that makes business so much fun
