[…]<p>> <i>Now it is true that the needs of human beings may seem to be insatiable. But they fall into two classes --those needs which are absolute in the sense that we feel them whatever the situation of our fellow human beings may be, and those which are relative in the sense that we feel them only if their satisfaction lifts us above, makes us feel superior to, our fellows. Needs of the second class, those which satisfy the desire for superiority, may indeed be insatiable; for the higher the general level, the higher still are they. But this is not so true of the absolute needs-a point may soon be reached, much sooner perhaps than we are all of us aware of, when these needs are satisfied in the sense that we prefer to devote our further energies to non-economic purposes.</i><p>[…]<p>> <i>For many ages to come the old Adam will be so strong in us that everybody will need to do some work if he is to be contented. We shall do more things for ourselves than is usual with the rich to-day, only too glad to have small duties and tasks and routines. But beyond this, we shall endeavour to spread the bread thin on the butter-to make what work there is still to be done to be as widely shared as possible. Three-hour shifts or a fifteen-hour week may put off the problem for a great while. For three hours a day is quite enough to satisfy the old Adam in most of us!</i><p>* John Maynard Keynes, <i>Economic Possibilities for our Grandchildren</i> (1930)<p>* <a href="http://www.econ.yale.edu/smith/econ116a/keynes1.pdf" rel="nofollow noreferrer">http://www.econ.yale.edu/smith/econ116a/keynes1.pdf</a><p>An essay putting forward / hypothesizing four reasons on why the above did not happen (We haven't spread the wealth around enough; People actually love working; There's no limit to human desires; Leisure is expensive):<p>* <a href="https://www.vox.com/2014/11/20/7254877/keynes-work-leisure" rel="nofollow noreferrer">https://www.vox.com/2014/11/20/7254877/keynes-work-leisure</a>
