A traditional view of markets is that they equalize wealth across individuals. A more recent literature suggests that markets are inherently disequalizing. A third viewpoint argues that initial history is crucial in determining whether inequalities persist or not. By constructing a theory of equilibrium investment allocation between human capital and financial assets in the presence of borrowing constraints, we address these views in a unified way. Two attributes of occupational diversity turn out to be central to our understanding: span, the range of training costs across occupations, and richness, the variety of different training costs contained within the span. The former is used to generate a necessary and sufficient condition for markets to be disequalizing, while the latter is shown to be directly connected to the question of history-dependence.
