[super Mario] What exactly is Bowser the ruler of? How can he afford elaborate traps/minions/castles?

He's the ruler of the Koopa Kingdom, according to most sources, which is where he gets his resources as well.

However, as revealed in Super Mario Bros. 3, they are all actors. He might still be King Koopa, but he can also afford so much because they're all props.
