> I've come to the conclusion that it's because many of them, especially the larger ones, face no real competition. All the other companies in their space are run similarly. I'd argue that a better way to describe this is that there is competition and possibly even a lot of competition, but all competitors have to deal with the fact that their employees are not perfect, management is not easy, teamwork is inherently hard and that over time every company accumulates its own set of weird workarounds and inefficient procedures, so this in itself does not lead to a competitive disadvantage.
