Where you have complexity, by nature you can have fraud and mistakes. You'll have more of that than in a company that shovels sand from a river and sells it.

There had been abuses in the 1920s. A joke going around then was the guy who said, 'I bought stock for my old age and it worked - in six months, I feel like an old man!' "It's tougher for you, but that doesn't mean you won't do well - it just may take more time. But what the heck, you may live longer."
