I'm not sure I agree with that proposition, at least in the general form in which it's stated.
Yes, the objective of any particular company is to make money. But is that why companies exist? We support the concept of a company, build laws and systems that allow one to be created. And clearly the reason we have those laws and system isn't so that the company can make money.
So the instrumental goal of a company is to make money, but the terminal value of companies existing is something different. Perhaps it's that they help us collaborate on issues that outscale any particular mind (though in that we have to be mindful of the Moloch [1] and keep in mind that corporations think in alien ways [2])...
If so, corporations exist to solve human issues primarily; and making money is only a measure of how successful they are at that.
