Governance is based on transparency and compliance with shareholder rights. It has nothing to do with fraud which is criminal behavior (intentional misrepresentation of a material fact). Your conclusion is an error. Most of American business, including RE, is run by decent people, like you. Islander.
How does this blog fit with your idealistic picture?

I disagree with you in general. I lived in Silly Con valley long enough to know how American business managers behave. Most of the management in America's big businesses are rotten to the core.
Fraud, or rather unethical practice, is done in three ways:
(i) collusion with Congress to change the laws to their benefit and then claiming that they behaved 'legally' (e.g. disclosure of stock option grants ,
(ii) misleading the owners (shareholders) of the company by making incorrect public statements (e.g. check TOL CEO's public statements last year about housing bust bottoming, while he was selling his own stocks like there was no tomorrow),
(iii) outright frauds (e.g. stock option backdating). In fact, even when they conduct outright fraud, they lead others to believe that it is 'standard business practice'.
