FWIW, there was a very good recent NY Times opinion piece titled "I Teach at a Business School. It's Time to Shut Them Down." by a professor at the University of Cambridge business school who argues that these schools have solely promulgated this idea of "efficiency" as their primary output to the detriment of society at large. Worth a read if you're interested in the topic.
Consider "The Red Queen" by Ridley book. It's premise is that evolution constantly improves a species, but since other species also are improving, the species runs and runs but stays in the same place.
It's the same thing in business. One has to relentlessly decrease the cost of doing business, because your competitors are doing it as well. You run and run and stay in the same place.
I haven't read the cited article, but the professor would need to show that industry profit margins are increasing to make his point. I haven't seen any evidence that margins increased in general.
