I hugely agree with your sentiment. But I think this case still stands. As opposed to the human "resources" that do the work, which management feels it must direct & organize & lead & regulate, the financial department often speaks the same business school language, is already aligned to the board-level/business-school goals of raking in barrels & barrels of money.

It's also largely a question of what change is required? I've seen a parent company move itself to become a subsidiary of a holding company which is now landed in another nation. It had almost no effect on the day to day. It was paper work.

Megacorps are filled with paperwork. But that doesn't necessarily mean they are bad at it, slow at it.
