A former professor and associate of my wife has developed a new field of which I am familiar with some elements. The field is Ecological Psychology, and he has written a book entitled, "Ecological Psychology: Creating a More Earth-friendly Human Nature." The book explores the ethics of maximization, and the author "deftly balances the contemporary drive for exponential economic growth against the insights of ancient spiritual tradition and concludes that 'the cultivation and expansion of needs is the antithesis of wisdom. It is also the antithesis of freedom and peace.'" http://ecopsychology.athabascau.ca/1097/howard.htm It's an interesting perspective and area of study. It also contrasts with excessive or conspicuous consumption which is so prevalent in the world today.
