QatariLady,

Sorry, you are right. I confused bribery and blackmail, I am not familiar with these things, yet still a bad example.

Bribes. Well bribes are bad for the economy and lead to the richer getting richer and the poorer getting poorer, hence will have an effect on society in the end. Surely it happens everywhere, yet on smaller scale has little impact and can not be checked, on governmental level it can spell disaster. Therefore in democratic societies bribery should be eliminated from the top down to create a competitive market.
