There's no such thing as a free market economy.

One has never existed and one could never exist. In fact, the idea that a free and fair (uncontrolled) market could exist is more utopian than anything you'll hear from any socialist.

The wealthiest in the world fo exactly the same thing. They just don't do it openly, in the way you would find under a traditional dictatorship.

More so, free market capitalism (even though it couldn't exist) is only one type of capitalism. So, it's far from rare but the industry standard for dictatorships, oligarchies and despots.
