I'd argue that business school does not teach that at all. That is a behavior taught by corporate sociopaths to other sociopaths being groomed. I base this on my business degree and 20 years at a major corporation. The distance between the two is enormous.
It’s not usually overtly taught, except at some elite business schools. It’s usually on-the-job training.
Same with human resources degrees. Unless you figure out that your job is to protect the company and not its employees, you’ll hit a glass ceiling on your way up the HR career ladder.
