Does this then imply some jobs are not intended to supply a living wage? Eg does that quants internship get a lower pay because they are expected to graduate beyond it? If so, how do we define what jobs are stepping stones and which are long-term careers?
I think all full time jobs should at a minimum pay a true living wage where one can live comfortably, save for emergencies, etc. If the job cannot pay that then it shouldn't exist. There are many ways to accomplish this beyond simply raising wages. Better government programs, lower the cost of housing/medical/transportation/food/etc. (these are surprisingly simple but many vested interests don't want this to happen),…
(Lowering the cost of essential goods and services is also something that can be done by leveraging the open market. It doesn't take yet another wasteful government program, which is the typical approach in socialist and social-democrat countries.)
