As a tongue-in-the-cheek retort, if the Greeks were really doing that (i.e. only playing ball in the grand building up of civilization), then the Roman Empire wouldn't ended up speaking Greek and looking so different in the period in which it is nowadays being called "Byzantine". Romans revered various Greek aspects, and somehow that privileged status that (everything) Greek enjoyed inside the empire played a role into the movement of the empire's capital to the Greek city of Byzantium (renamed Constantinople). It surely feels more like taking (the reigns, and not doing much afterwards, other than holding out for as long as possible).
