I'd suggest you read about managerialism, our reigning business paradigm. Spender and Locke's "Confronting Managerialism" really opened my eyes. If you think of management's purpose as making the business better, there's a lot that doesn't make sense. But it gets clearer if you think of it as caste dedicated to both individual and class power and enrichment, who also try to keep the business on the rails enough that there's something to have power over and extract money from.

Not that all managers are bad or anything; plenty of them are people just trying to get things done. It's a structural problem.
