incomes than are available elsewhere arise in a particular sector, individuals in other sectors will quickly switch their resources to the more profitable one until, as a result of competition, profit and income levels reach the mean of other sectors, at which point there is no longer an incentive to shift to it. In the long run, therefore, a pure market economy should be one without sharp inequalities. As a consequence, no-one will be able to use extreme wealth to accumulate political privileges.
