Both these impacts should have a clear effect on the present model, but will not be explored here. If one imagines that, at the beginning of the development process, all workers are unskilled and earn an unskilled wage (which is most likely to be the reservation wage) and that at the end of it, all become skilled workers and earn a skilled wage, then over the process, when an increasing number of workers must move from the unskilled to the skilled sector through education, income inequality must first rise and then fall. Thus, if one accepts the characterization of the essence of a full development process as embodied in the model, then the Kuznets hypothesis is clearly right. The key point here is full development.
