huh...that's weird. I guess it depends on where one goes to school. This for sure is not what I got out of my business classes.
Most were how to keep employees, even low-wage employees, how to make them happy despite low wages...
I think also, just because a b-school says this, we all have our own minds. There's a lot of other stuff to learn in b-school that is helpful, at least it was to me. The stuff I don't like, I just don't pay attention to it.
Most of the classes that I took in business school were and are invaluable to me. But, I read other stuff other than what is in b-school, there are a ton of books that say how to treat employees right, how to use them as a marketing assist to help what customers want, and all that.
We go to school to hopefully learn how to learn - how to be autodidactical.
Let's all temper our expectations. Get knowledge from multiple places. Reject what you don't want, keep what is useful and ethical to you.
I never understood the hate people have for different majors. Some hate b-schools, some hate computer science majors, some hate art, some hate etc, etc, etc.
Chill, everyone, learn where you can. Accept and reject specific items as you see fit. It's all good.
