There are several historic approaches to creating work for people that the market economy does not want. 

One is supported employment for people who meet traditional criteria for cognitive disability. 

Another is public works, from Egyptian pyramids to Roosevelt’s PWA. 

A third is the US military and civilian organizations that favor veterans, such as the US postal service and Veterans Hospital Association. 

The last is the dominant method of creating socially acceptable non-college employment. The techniques used in the vast industry could be the basis for future synthetic employment.
