Politicians fool people so they can get votes. Crooks fool people so they can lie, cheat and steal. Crooked politician is almost a perfect term to use, although there are some minor exceptions. Crooked businessman is also a perfect term to use for basically the same reason. It boils down to racketeering and rackets which are two of the foundations of civilization as we know it. Just a guess, but I think enslaving women might have been the earliest protection racket. One group of men raped and pillaged women and the women sought protection from other men, and that's how the racket came to be. Women did the domestic and field work while men goofed and went on hunting trips. The early male conflicts of the time were basically symbolic gestures against other males. The unfair and unequal sexist "contract" continued until now. As females and other slaves became property which could be traded, bought and sold, male conflicts turned into wars. Human history is the story of rackets and racketeering in all its forms.
