Why amoral? If a an employee costs the company more than they make, it means the owner of the company is essentially donating his money to the employee. Is it amoral to not do that? What if the owner wants to donate the money to cancer research instead?

To expand on this, a company’s purpose should go beyond simply generating profit for its owners, imho; among other things, it should also include a duty of care toward its employees. Society instills a strong work ethic in us from childhood, teaching us that contributing to the greater good is our individual duty. Before the plague of neoliberalism, there was an expectation that companies would have a positive impact on society, too. Nothing, except greed, forbids to return to those values.
