What do you mean by 'profit inefficiency'?
> Corporations as viewed from the inside are wildly incompetent [...]
Corporations have varying levels of efficiency. MNCs are by and large _fairly_ competent.
Of course, if you see them from the inside, there's still enough weird and incompetent stuff going on.
Compare to how western militaries have their fair share of screw ups, but they still wipe the floor with non-western militaries, whenever there's any conflict.
There's plenty of studies comparing the quality of management in local companies versus multinational corporations. See eg https://www150.statcan.gc.ca/n1/pub/11f0019m/11f0019m2020008...
