Reminds me of reading the book "The Honest Truth About Dishonesty" by Dan Ariely. It's a good read to hear about how dishonesty and cheating can perpetuate throughout a company to the very top. Also, watch "Inside Job" to hear about how corrupt banking firms brought about the 2008 financial crisis. According to the movie, earning money triggers the same part of the brain as cocaine does. Some of the CEOs of these firms had vices like drugs and prostitutes, which makes me wonder if they got the same high from those activities as they did taking big risks.
But... Not everyone in business cheats and is dishonest. I think just some bad business people give others a bad name.
