Godfather and Politics
The Godfather, the head of the Mafia, played by Marlon Brando, would help an acquaintance needing a favor and say, "some day, and the day may never come, I will call upon you to do a service for me."
This is exactly what the oligopolies, both corporations and unions, do with our representatives in Washington. They give them campaign bribes and in return expect, and receive, favors in the future. When the Godfather asked for a favor, no one refused.
