What responsibilities do companies have to future generations or societies?

I think that much of this answer is contingent on how one
views the function of business stakeholders.  On one hand, if management has a stake in
the company, if they see the company as a reflection of their own ideas and ideals, then
perhaps, the business will be seen as a part of a social setting.  It might be that such
businesses will see their role as one of contribution back to society and to help others
both now and in the future.  At the same time, if management does not see itself as
having a stake in the company, does not see itself as wedded to the principles of the
company's success, it might be less likely to view itself as a part of a present and
future society, and become more likely to serve its own interest than one of a larger
vision.  In the end, the role of management in the function of a company becomes a
critical part to this equation.
