The ruling of that Supreme Court case was that publicly-traded companies are obligated to act in the interests of their shareholders, rather than employees or customers. Cargo cultist MBA-types -- those who have superficial knowledge, but lack actual understanding -- think that means companies must be purely sociopathic and slavishly work to increase quarter-to-quarter stock returns at all costs, but that's not actually true because management is still allowed to take things like long-term stability and customer goodwill into account.
