Because business school also trains them to minimize costs and maximize quarterly profits. And their managers and stockholders reward them for that as well. Which inevitably leads to that behavior and a bunch of other idiotic ones. Because as you demonstrate with the bit about fixed costs, a lot of these numbers are fictions. Sometimes convenient fictions, but always fictions.
This is in contrast to the Lean approach where one minimizes waste and maximizes value delivered to the end user. In Lean thinking, staff aren't a cost to be shed ASAP, they're an asset, one you invest in.
