Most of our waking hours are spent while we earn and learn. And over time, human nature is moving towards more learning and less emphasis on earning. At least that is true for most people. Some however are totally fixated on earning as much as possible, not caring much on what they need to do to get there.
Once we move into a society that focuses predominantly on the learning, we will pretty soon be in a situation where earning is no longer required. Simply because technology will be developed to such an extent that manufacturing can be done by machines way cheaper than before!
