ABSTRACT
This chapter intends to construct a simple model to illustrate the way in which these interconnections between high and low earning capacities and between high and low savings ratios may end in the formation of a society which is intermediate between a Propdem and a Plantcap—that is to say, in a Propcap. It considers a society in which there are a limited number of distinct social classes. There is no class distinction between the life-cycle patterns of childhood, working life, and retirement; and all citizens have the same fertility and mortality rates, so that there is also no class distinction in the size of families and the rate of population growth. The members of the different classes do not, however, intermarry. Finally, citizens help only their own parents or their own children; there are no interclass transfers of property and no death duties or other taxes.
