Peter Lewin, with a good reminder of how profit is a good thing:

We don’t get the meat from the butcher because of his benevolence; but rather because he is intent on “maximizing” his profits, or, in other words, he does the best he knows how, to make his profits as big a possible within the constraints that he faces – including┬álegal and moral constraints. It is not that he is greedy or uncaring. He may be, but he may be a wonderfully compassionate and generous individual. But deviating from his endeavor to maximize his profits may put him at a disadvantage to his competitors and leave us with less meat, from him.

But don’t forget, profit is merely a scorecard of how well a business serves its true purpose of creating a customer.
