I'm sorry that you have such a cynical view of the world. Fortunately, many people (including people who make decisions about laws and regulations) disagree with you.
1. Remember Enron? Lehman? Arthur Andersen? WorldCom? Parmalat? Countrywide? I could go on. I suppose the rule is "you're an amazing entrepreneur (unless you get caught)"?
2. It's you and me who pay the price when these companies collapse.
