So, I saw this movie, which was based on this book.
Having seen the movie, I'm amazed, awed, and appalled. The movie tells a story of a company that started out shady and then encouraged a culture of increasinly risky, decreasingly ethical practices. It's tempting to try to consolidate the blame into a few execs acting in bad faith, but I suspect it's more accurate to see systemic evils, throughout the company - on to the bankers who supported the scheme, and on to a lesser degree to the heady investing culture that can't get enough of a "too good to be true" stock story.
Not to say all the people under the Enron moniker are evildoers. Not to say that all investors are money grubbing and amoral. The review I read before going to see this movie is that it would make me mad. I think it left me sick to my stomach more than really angry. Close enough, I guess.
