The idea underlying all interventionist policies is that the higher income and wealth of the more affluent part of the population is a fund which can be freely used for the improvement of the conditions of the less prosperous. The essence of the interventionist policy is to take from one group to give to another. It is confiscation and distribution. Every measure is ultimately justified by declaring that it is fair to curb the rich for the benefit of the poor. In the field of public finance progressive taxation of incomes and estates is the most characteristic manifestation of this doctrine. Tax the rich and spend the revenue for the improvement of the condition of the poor, is the principle of contemporary budgets. In the field of industrial relations shortening the hours of work, raising wages, and a thousand other measures are recommended under the assumption that they favor the employee and burden the employer. Every issue of government and community affairs is dealt with exclusively from the point of view of this principle.

The interventionist in advocating additional public expenditure is not aware of the fact that the funds available are limited. He does not realize that increasing expenditure in one department enjoins restricting it in other departments. In his opinion there is plenty of money available. The income and wealth of the rich can be freely tapped. In recommending a greater allowance for the schools he simply stresses the point that it would be a good thing to spend more for education. He does not venture to prove that to raise the budgetary allowance for schools is more expedient than to raise that of another department, e.g., that of health. It never occurs to him that grave arguments could be advanced in favor of restricting public spending and lowering the burden of taxation. The champions of cuts in the budget are in his eyes merely the defenders of the manifestly unfair class interests of the rich.
