(morals and ethics have always been tools for subjugating the lower classes) It bonds them and as they enable each other in creating a reinforcing spiral.

It's universal. The "bunga bunga" parties of late PM Berlusconi are no different and take a good look at Eton's long track record of Boris Johnsons and many more of the likes.
