Hey, I'm in Econ and we briefly went over Keynesian economics. I agree that most of Keynes' concepts we went over are believable, however, his concept about the obligation of society to provide employment to individuals in field that they are educated or have experience in. What are the prominent theories that are available about how society/government should provide jobs where there is a lack of demand? Roads can be built, parks can be monitored, street sign and cones can be manufactured but this leaves a whole myriad of other jobs that are determined directly by demand such as nursing, engineering etc...
