Why not? People are people and I seriously doubt we have changed that much as a species since the Roman times. Yes social and moral adjustments have been made, but people then are still the same creatures as we are now and the same ideas, choices, concepts and basic fundamentals are still as valid then as they are today. Heck just look at the school playground - easiest way for anyone to bully themselves into a position of power is to beat on anyone and everyone who would dare to oppose them, whilst also ensuring that the targets they select are a group who (individually) would be unable to mount much of a reprise against them. Works at the school playground level and at the national level - although the tools and methods shift somewhat.
