Yes, emulating what they see in politics. That is a good point. Except...it's not. Lying and cheating in politics have been going together since people first lived together - it's not a Clintonian innovation despite what some conservatives minds like to think.
Furthermore, people always like to bemoan the present and nostalgize the past into a creamy past of delectable good tastes, strong morals and values, better, happier, safer et cetera. It's silly. 403, while you many not have cheated, I am 20 years old and I have never cheated either. But I am sure there are similar percentage's of our generational peers who did.
