Kevin Drum explains:

We live in a complex world, and that means the rules are sometimes complex too. But they don't have to be anywhere near as complex as they end up being. We could have a simple tax code, simple environment rules, and blunt financial regulations. We could probably cut the size of agency regulations by 10 times if we wanted to. But businesses don't want to. Sure, they'd prefer no regulation at all, but they know that's not in the cards. So in public they bemoan complexity, but in private they fight endlessly for more of it. To their lawyers, every single extra page is an extra opportunity to make more money.

Veronique de Rugy takes Drum's argument in another direction. Drum pushes back.
