That Rep. Alexandria Ocasio-Cortez, D-N.Y., isn’t quite up to speed with the realities of capitalism is one of those things we already know. That she’s not quite got the most basic understanding of simple economic concepts wasn’t quite so apparent, not until she decided to question the Wells Fargo CEO at least. She asked Wells Fargo CEO Timothy Sloan why Wells Fargo shouldn’t be held responsible for a leak in the Dakota Access Pipeline. His answer, that they didn’t operate it so weren’t responsible for it, didn’t seem to please the freshman member of Congress.

But the question itself betrays an ignorance of how large scale projects have to work. It’s to question that very idea of limited liability which is the only way we can have a large-scale economy.
