From The Road to Oligarchy by Daniel Greenfield in Sultan Knish
The oligarchy safeguards established interests. It is a mafia whose goal is to control and profit from all wealth. Even when it comes to power as the result of a revolution, it very quickly discovers its own established interests. Its members will knock each other off, but they all agree that the basic nature of the system should not change. What they fear most of all is the collapse of that system.
There is plenty of money to be made in an oligarchy, but there is very little forward motion. New things do not emerge out of an oligarchy of union guilds, politically connected tycoons and politicians who derive their power and influence from their connections to both. Once a new thing exists, then the oligarchy will find ways to profit from it and even improve it, but there is no progress from within the oligarchy.
