It is interesting how the advocates of social inequality think that the wealthy respond to quite different incentives from the poor. If the rich are to be persuaded to work, they require the stimulus of still greater wealth: hence the paramount importance of reducing taxes on high incomes. When dealing with the poor, in contrast, it is held that there is nothing like the prospect of still greater poverty as a work incentive: hence the paramount importance of strictly limiting the benefits to which they are entitled.
