Have you ever hired, worked with, met, talked to or at least seen the bill from a top corporate attorney? They're expensive for sure, but not that expensive. Much of the cost of those cases comes from the army of junior associates reading through thousands of pages of evidence, etc.
Didn't mean to be flippant as I'm not an expert either, but through the course of my career I've spoken to a ton of attorneys including a few who routinely represent companies all of us know well. The top corporate litigators I've met charge in the $1000/hr range, but not much more than that. Their rates tend to be somewhat negotiable as well depending on the task.
