I don't think you sign up for the life JB and M set up unless you're a person who's a big control freak who not coincidentally also fears, distrusts (and probably several other negative verbs...) anybody who isn't exactly like you (because people not exactly like you make you see that you're not totally in control...) ......Then your isolation probably feel safe, righteous, etc.
Then, you produce a bunch of other unwitting people (mostly as babies, some possibly as marryers-in whose vulnerabilities you unconsciously recognized as potentially predisposing them to live in this kind of situation...). And you train them up from day one to see everything in the same fearful, distrustful, etc. way that you do -- and maybe even more so....You drum it into them.....So they go along with it because they've been programmed to think it's the only way to live. And you now have a group of people who constitute a social circle for you -- and you've trained them from birth to submit to your controlling them in all kinds of ways that people not brainwashed-from-birth to do it would likely never let you control them ....
And there you have a kind of ideal situation (for fearful, distrustful, etc., control freaks, that is....)
All the fun you need is engaging in group paranoia and pushing around your trained-from-birth pushable retinue. You're not just okay with it. You feel like a goddamn little king or queen on earth.....You've got a moat and a bunch of slaves. Who could ask for anything more?
Been there. Done that. They are very warped people. And they like this. Whereas they wouldn't like "normal" life a bit.
And they screw up the slaves for a lifetime. Both the ones who escape and the ones who can't manage to get away, including -- maybe especially -- the ones who imagine they don't even want to get away.
