By buying a good or service, the buyers (consumers) demonstrate that they prefer this good or service over the sum of money they must surrender in order to acquire it. In contrast, politicians, parties, and civil servants produced nothing which is sold in markets. No one buys government “goods” or “services”. They are produced,  and costs are incurred to produce them, but they are not sold and bought. On the one hand, this implies it is impossible to determine their value and find out whether or not this value justifies their costs. Because no one buys them, no one actually demonstrates that he considers government goods and services worth their costs, and indeed, whether or not anyone attaches any value to them at all. From the viewpoint of economic theory, it is thus entirely illegitimate to assume, as is always done in national income accounting, the government goods and services are worth what it cost to produce them, and then to simply add this value to that of the “normal”, privately produced (bought and sold) goods and services to arrive at gross domestic (or national) product, for instance. It might as well be assumed that government goods and services are worth nothing, even that they are not “goods” at all but “bads”, and hence, that the cost of politicians and the entire civil service should be subtracted from the total value of privately produce goods and services. Indeed, to assume this would be far more justified. On the one hand, as to its practical implications , the subsidizing of politicians and civil servants amounts to a subsidy to produce with little or no regard for the well-being of one’s alleged consumers, and with much or soul regard instead for the well-being of the producers, i.e., the politicians and civil servants. Their salaries remain the same, whether their output satisfies consumers or not. Accordingly, as a result of the expansion of “public” sector employment comma will be increasing laziness, carelessness, incompetence, disservice, maltreatment, waste, and even destruction–and at the same time ever more arrogance, demagoguery, and lies (“we work for the public good”).
