They have lives that are enjoyable, but I suspect that they don't particularly enjoy it. I think they truly believe the BS they're selling, and that must be incredibly frustrating. The world just won't quite seem to bend to fit their view and they are therefore constantly in conflict with reality. That probably doesn't make for a good time
That said, if they really don't care and it's all about business for them, then I'm sure at least some of them enjoy it. They don't all seem to be quite as full of themselves as AMIII, so I'm not sure I could say that they're all "in love with themselves." If they can put aside the fact that their worldview doesn't mesh with reality and just enjoy having all their needs taken care of and being adored by millions, then they should be having a pretty good time.
