Motivation in an RBE - again

Once we have stopped doing work for its own sake, even if we have automated much of the remaining and truly necessary work, there will be the need for human input. Even Jacque Fresco and Peter Joseph accept that there will always be a residual need for human input even in the ultra-automated - 'cybernated' world they imagine when arguing for an RBE.

We seem to have the assumption that people are only motivated by money, but this flies in the face of many facts or apparent facts:

• There are many people working philanthropically who are plainly motivated by doing good rather than by money. Some do good in their professional capacity, some in their own time. If the latter could be freed up from doing whatever they have to do to get paid, to doing what they want to do, there would be step change in doing good.
• People drop out of the rat race - including from highly paid jobs - and not all go off to 'find themseleves' - many take up careers that they believe are more worthwhile.
• Money in itself cannot be an incentive, because it is useless until you buy something with it. Being motivated by making money (over and above what is necessary) is in effect being motivated by having more, or a prior, call on goods and services than other people. Is this really the motivation we want for our society?
• The studies explained by Daniel Pink in his TED talk (which can be seen on internet video sites), and other work.

If we were to have a money-free world, and some problem with motivation were perceived, would we bring back money as an incentive, or would we try to find other motivational means?
