I don't agree, though I guess it depends on how long long is. There are certainly some examples I can think of but I would argue most of them are actually natural monopolies in disguise, usually benefitting from network effects I 100% grant that large organizations by their nature are less efficient than small organizations due to lossy communication. And some companies have a minimum size due to the nature of their work, which places inherent limits on their efficiency. But they're still subject to competitive pricing from other, similarly large companies.
