That's was how I answered a question about "the effects of market incentives", it was a course about social and ethical responsibilities in my MBA program.
I do completely agree with the statement: “profit is the reason for
businesses to exist” and the only way to explain why is with examples.
The most powerful stakeholders who influence the business decision
making are those who finance it; shareholders, and their ultimate goal from
investing money in business is to generate return on their investment, if
there’s no satisfactory return, the decision makers in the company will face
the possible threat of shareholders withdrawing their investments.
