And let's not forget the cultures where there's a term "con artist".

Also, we'd need to define what is cheating, or what is socially acceptable cheating. I remember when we were buying that house, the agent has promptly created an atmosphere of deadlines approaching, and then telling us at each step one more thing we need to get, not telling us everything in advance, so that on each of those things we didn't have the time to shop around. Ended up buying insurance for $1600 from her friend (who turned out to have no address, no offices) and later switched to State Farm for $600. Or all those guys who sell stuff which is available for free, like "how to fill FAFSA forms" (but they don't call it that). Or the honorable occupation of used cars sales, or designing products with inferior materials which hold for 13 months and then may break anytime. Or the rebate scam pulled by many (in my experience, top player in the field is HP).
