Wealth is an abstract concept. In nature noone owns anything. Its society which gives rise to law which gives rise to property and money which gives rise to wealth. if its not working for most people society has the right to decide to try another way. Given that more and more economic value is being created by machines whose income accrues only to the owners of the machines and not to entire society (though without society we would still be hunting and wearing skins so no machines would have been invented); we may need a new system. A star trek kind of society where people's basic needs are taken care of by the output created by machines (which are owned by society as a whole) and people work for prestige and luxuries. This can work in a society where 90% of the economic output can be provided by machines and you only need humans for 10% of the creative jobs. For such jobs a human who doesnt have to work but wants to do the work will be much more productive. The humans who dont want to work will be bored and eventually stop reproducing so the problem will solve itself over 5-10 generations in a humane manner.
