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 it’s product and workforce, 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.
