>I have no idea how they could have been so bad while employing so many people
There is a significant correlation between how many people you employ and how much nothing you accomplish. It means you've gotten big enough to survive long bouts of doing something and achieving nothing with large amounts of people.
Amazon empoloys 300k corporate employees. Apple has 170k. How is this a significant correlation.
It seems there's literally no correlation between people and what is accomplished.
