And there is more than one way to achieve that 'value'. Your mindset of 'we are justified in efforts to extract every possible penny of profit' as the absolute rule for all business decisions is not true. If it were, company's would be lambasted for doing things like offering employee benefits, or contributing to charitable efforts, and every business would be pinching every possible penny. The reality is businesses can and do setup with Corporate Values and beliefs. Public Officers have a fiduciary duty to serve the shareholder's interests - that does not unilaterally mean extract maximum dollars in a finite view.
When Google pulled out of China, it was a decision that meant Google walked away from millions and millions of dollars. It was a move driven by long term corporate beliefs about what is RIGHT for the company to represent and take a stand over for the long term success of the company and as an essential citizen of the global internet. That is a simple example of how officers can make moves that serve the corporate interests without looking only at the short term dollars. The list of these kinds of examples can go on and on. Fiduciary duty is not simply "maximum profits NOW"
No, that simplified view just makes you part of the problem when it comes to irresponsible behavior and leadership. Thank god there are many companies still that realize long term success comes from balancing the needs of employees, community, customers, and investors.. and not just the last one.
