To me it seems pretty obvious that it would be simple to build a business around helping people achieve autonomy, a feeling of competence and relatedness. In fact, every web company that has been successful thusfar has their business build solidly on one or all of these. And I believe that as people discover that these things are within their reach, they will gravitate more and more towards companies that offer tools to helping them achieve happiness.
