The con is a kind of jiu-jitsu that turns the sucker's own greed into its principal weapon. The greedier you are the more likely you are to be conned, and for the greater a sum.

Institutionalized wishful thinking - the stock market, religion, advertising - is after all a cornerstone of our system.
