Surely if you already have total control over so many people you don't need tricks.

Are you serious?

The global control racket is a trick. Corrupt western democracies are a trick.

The banking system is a trick.

The propaganda media system is a trick.

Real power is with the billions of people that inhabit the world.

The trick is fooling the masses into following the orders of a few.

If the average person understood how things really are, then there would be a revolution overnight.

They know this, so they make changes slowly so they don't upset the balance of fictional control vs. actual control.
