Capitalism, in my view, has become or at least is becoming a victim of its own success. All existing economic systems focus primarily on production and distribution of scarce resources, and most people's link to existing economic systems is through work. However, the advance of technology is rapidly bringing us to the point where many resources are not scarce at all and can be produced with little or no human labour. 

We are going to need a new economic system, one that is able to provide everybody with access to resources even though they don't work  and there is no work for them to do. Some science fiction writers have speculated as to what such a system could look like, but I am not aware that any serious economist has done any work on the issue.
