*sigh* Do you know nothing about the Covenant belief system? At one time the Elites and Prophets were at war, but then the Prophets found some sort of Forerunner artifact, and they found what they thought was evidence of the Halos, and what the Halos did. They thought that the Halos would, basically, send them all to some glorious afterlife. So the Prophets made a covenant with the Elites. The Elites would protect the Prophets, and in return they would send all of them to this afterlife. They Forerunners were soon considered as gods, because of the magnificent artifacts and of course Halo. So the Prophets decided to use the Forerunner tech, and gain their knowledge. Over time other races were absorbed (or conquered) into this belief system, and the combination of all these races was called the Covenant. So you see, they follow this rigid caste structure because they do it for their place in the afterlife.
