Way back in Econ 101 the prof asked 'What is the purpose of capitalism?'. I responded something like to provide the greatest number of goods at the lowest cot for the most people.
He pointed his finger at me and said sharply 'No ! The purpose of capitalism is to make a profit'.
It took years on the job for that to fully sink in.
That is true but simplistic. The way to make a profit is to supply a good or service that the customer wants and at a price the customer is willing to pay. It is a meeting of minds between the producer and consumer. (how much effort and expense are you willing to put in for the price you charge and how much is the consumer willing to pay for the final product? - when these two meet, there is a sale.) Also, since there is competition from other producers, the price and quality needs to be competitive to attract the consumer to your product or service rather than the competitor's.
It's also simplistic because it assumes that there's an economic model called 'capitalism' with an intentional origin, that's separable from human nature. IOW, that humans had anything to do with 'capitalism's'arrival, and the global economy not instead being an emergent property of how we organize ourselves.
'capitalism is to make a profit'?
To be alive is to acquire resources for one's own survival and reproduction. Yes we're a social species and community has become a part of that, but 'profit', or more simply, acquisition of needed goods for survival is inherent in what it means to be alive.
You can try to improve the model, but you can't extract human nature from it. And the model isn't 'capitalism', it's people solving problems for material gain, which has been central to every way of life in history.
