One of the most widely accepted propositions among political economists is the following: Every monopoly is bad from the viewpoint of consumers. Monopoly is understood in its classical sense to be an exclusive privilege granted to a single producer of a commodity or service, i.e., as the absence of free entry into a particular line of production. In other words, only one agency, A, may produce a given good, x. Any such monopolist is bad for consumers because, shielded from potential new entrants into his area of production, the price of the monopolist's product x will be higher and the quality of x lower than otherwise.
This elementary truth has frequently been invoked as an argument in favor of democratic government as opposed to classical, monarchical or princely government. This is because under democracy entry into the governmental apparatus is free — anyone can become prime minister or president — whereas under monarchy it is restricted to the king and his heir.
However, this argument in favor of democracy is fatally flawed. Free entry is not always good. Free entry and competition in the production of goods is good, but free competition in the production of bads is not. Free entry into the business of torturing and killing innocents, or free competition in counterfeiting or swindling, for instance, is not good; it is worse than bad. So what sort of "business" is government? Answer: it is not a customary producer of goods sold to voluntary consumers. Rather, it is a "business" engaged in theft and expropriation — by means of taxes and counterfeiting — and the fencing of stolen goods. Hence, free entry into government does not improve something good. Indeed, it makes matters worse than bad, i.e., it improves evil.
Since man is as man is, in every society people who covet others' property exist. Some people are more afflicted by this sentiment than others, but individuals usually learn not to act on such feelings or even feel ashamed for entertaining them. Generally only a few individuals are unable to successfully suppress their desire for others' property, and they are treated as criminals by their fellow men and repressed by the threat of physical punishment. Under princely government, only one single person — the prince — can legally act on the desire for another man's property, and it is this which makes him a potential danger and a "bad."
