The Austrian Case Against Economic Intervention – Ludwig von Mises Institute Canada.
The basic unit of all economic activity is the un-coerced, free exchange of one economic good for another based upon the ordinally ranked subjective preferences of each party to the exchange. To achieve maximum satisfaction from the exchange each party must have full ownership and control of the good that he wishes to exchange and may dispose of his property without interference from a third party, such as government. The exchange will take place when each party values the good to be received higher than the good that he gives up. The expected, but by no means guaranteed, result is a total higher satisfaction for both parties. Any subsequent satisfaction or dissatisfaction with the exchange must accrue completely to the parties involved. The expected higher satisfaction that one or each expects may not be dependent upon harming a third party in the process.
Several observations can be deduced from the above explanation. It is not possible for a third party to direct this exchange in order to create a more satisfactory outcome. No third party has ownership of the goods to be exchanged; therefore, no third party can hold a legitimate subjective preference upon which to base an evaluation as to the higher satisfaction to be gained. Furthermore, the higher satisfaction of any exchange cannot be quantified in any cardinal way, for each party’s subjective preference is ordinal only. This rules out all utilitarian measurements of satisfaction upon which interventions may be based. Each exchange is an economic world unto itself. Compiling statistics of the number and dollar amounts of many exchanges is meaningless for other than historical purposes, both because the dollars involved are not representative of the preferences and satisfactions of others not involved in the exchange and because the volume and dollar amounts of future exchanges are independent of past exchanges.
