Thanks is the reward.  Thanks is the only currency.   Thanks in a truly civilized society is our end to means.  With kind people, exercising ones ability and volunteering demonstrations is the care which spreads love around the world several billion fold, comes naturally.  One does not need to be forced to work.  Being paid to work is demeaning. We are billions.  We would be slow and ineffienct to fight each other.  We must use our technologies to collaborate, share ideas and be together in a world ensuring the best survival to any human whom wishes to experience it.  We are billions and should have each others backs and when thanks is given, it is magical for the effort well done.
