Thing abouty oligarchies is there are always new people making money and breaking into the ruling class by bribery or marriage (see Roman Empire on which Ultramar is based). As for the Imperium... well the thing about corrupt bureaucracies is they can be played. Churches with massive clergy also provide an avenue for self-improvement (see Medieval Catholocism) and even the military allows one to rise - if you survive.
