Did they? I'm under the impression that it's a small country with a distinct upper class. The right people live in Wassenaar and Bussum etc. with ludicrous property prices and have all the influence.

They are good at camouflaging inequality and other things. The lower classes get enough to get by, so it isn't obvious. The rich don't brag, wear cheap suits and look like regular people.

But the old-money royalty is obvious, and probably just very good at hiding corruption.
