There is no such thing as making “enough” money under the chicago-school dominated business thought. A business should always make as much money as it can for its investors, always. A friend who read Friedman’s works says that the Friedman doctrine makes room to say that a wise business will optimize investor outcomes by investing in its product, workforce, and other smart long-term choices, but in practice, nobody ever reads that deep into the Friedman doctrine. It’s just “philosophical” license to make (and demand, on the part of investors) the shallowest slash-and-burn business decisions possible to make line go up NOW. I will accept arguments about how it’s capitalism, but I’d like to point out that we experienced a very distinct culture shift in business leadership starting around the time that Chicago school thought became all the rage.
