This paper presents a simple model of distribution dynamics, in which the d
istributions of wealth, education and political power are circularly endoge
nous. Different levels of education translate into different income and wea
lth levels. Political power may (or may not) vary with wealth, and in turn
affects decisions on the level of public expenditure on education. Since th
e market for education credit is imperfect, some people might need to rely
on public schooling, the quality of which depends on those expenditure leve
ls. As a result, educational opportunities differ along the wealth distribu
tion. The dynamic system displays multiple equilibria, some of which are ch
aracterized by a vicious circle of interaction between educational, wealth
and political inequalities. These particular equilibria, which are more une
qual, are also shown to be inefficient in terms of aggregate output levels.
Switching equilibria may be achieved through redistribution of political p
ower.
