This paragraph encapsulates it pretty nicely:

"In the financial press you're called a "rogue trader" if you're some overperspired 28 year-old newbie who bypasses internal audits and quality control to make a disastrous trade that could sink the company. But if you're a well-groomed 60 year-old CEO who uses his authority to ignore quality control and internal audits in order to make disastrous trades that could sink the company, you get a bailout, a bonus, and heroic treatment in an Andrew Ross Sorkin book."
