The American economic system not only encourages greed and dishonesty, but makes much of it legal.
It was not illegal for the Enron execs to dump stocks when no one was looking. And legally they kept 100% of the profits. Also, most of these large compaines do not and have never paid taxes. The larger the company the larger the taxes breaks and bonuses until the gov't is actually paying THEM to stay in business.
Lastly, since dayum near any expense can be written off, there is no accountability as long as a company appears to be profitable. And where there is no accountability, corruption will go unchecked. I am still surprised that Martha Stewart got bagged, wonder who dropped the ball on that one.
