To be clear, there’s a difference in terminology of profit in economic context vs colloquial. When they say profit / non-profit, non-profit doesn’t mean that people don’t make money for their work. Rather it refers to what’s done with the extra money made above the costs of the firm, after it’s paid its employees and officers. Is it given to the firm’s shareholders, is it reinvested into the firm, are prices reduced to have less excess the next quarter, etc.
