Mind controllers like to live in secret, and I think that is a large part of their problem. Spending your life keeping tremendous secrets must be a real pain in the ass, and if they have to live in some claustrophobic bunker network on top of it all - that's even worse.
I get to wander the streets of New York City and visit 10 different starbucks'ses within a 5 block radius. Mind Controllers, my heart goes out to you.
