Well, yeah. That's the whole point of being in a peerage. You raised your level to be a High-Class Devil, and then your subjects do the same when they serve under you. Ultimately, the goal is when everyone is High-Class or Ultimate-Class. Odds are that Diehauser and Rudiger's teams are filled with High-Class and Ultimate-Class Devils, because they are some of the strongest devils in the Underworld.

Like it was mentioned above, the real influence in the Underworld are the titles of the 72 Pillers, not the Satans. You could argue that Zekram, or his descendant Lord Bael, are probably the real forced behind the Underworld. That being said, there is a "common mass" element to all of this. Even though the Purebloods humor the Satans for the sake of popular public opinion, it seems they fear losing their influence.

Something that is probably going to collapse is the purist standpoint of the Anti-Satan Faction. I almost feel Sirzechs and Ajuka are trying to do this by powering up Issei. Its an attempt to show that blood purity and demonic powers aren't the best around.
