John Mackey, the CEO of Whole Foods has a blog and on it there’s a re-print from Reason magazine of a debate he had with Milton Friedman (famous and influential economist) and TJ Rodgers (CEO of Cypress Semiconductors) about the concept of corporate philanthropy.  You can read the whole thing here.

Here’s a couple of the intro paragraphs:

Thirty-five years ago, Milton Friedman wrote a famous article for The New York Times Magazine
whose title aptly summed up its main point: "The Social Responsibility
of Business Is to Increase Its Profits." The future Nobel laureate in
economics had no patience for capitalists who claimed that "business is
not concerned ‘merely’ with profit but also with promoting desirable
‘social’ ends; that business has a ‘social conscience’ and takes
seriously its responsibilities for providing employment, eliminating
discrimination, avoiding pollution and whatever else may be the
catchwords of the contemporary crop of reformers."…

John Mackey, the founder and CEO of Whole Foods, is one businessman
who disagrees with Friedman. A self-described ardent libertarian whose
conversation is peppered with references to Ludwig von Mises and
Abraham Maslow, Austrian economics and astrology, Mackey believes
Friedman’s view is too narrow a description of his and many other
businesses’ activities. As important, he argues that Friedman’s take
woefully undersells the humanitarian dimension of capitalism.

In the debate that follows, Mackey lays out his personal
vision of the social responsibility of business. Friedman responds, as
does T.J. Rodgers, the founder and CEO of Cypress Semiconductor and the
chief spokesman of what might be called the tough love school of
laissez faire. Dubbed "one of America’s toughest bosses" by Fortune,
Rodgers argues that corporations add far more to society by maximizing
"long-term shareholder value" than they do by donating time and money
to charity.

If you don’t already you should also read/subscribe to Reason, the original source of the debate.  It consistently runs some great stuff.
