At the end you mention the quality-of-life factor. This brings to mind Maslow's hierarchy of needs: physiological, safety, belonging and love, esteem, and self-actualization from bottom to top. At the bottom of this pyramid are the more physical factors, at the top the more sublime. Someone continuously concerned with feeding his family will have no interest in spiritual evolution for himself or others.

Someone whose Steem life is devoted to the upper part of the pyramid (I work in the self-actualization space) will have a far harder time reaching a responsive audience than someone who blogs about food, for example.
