Anti-trust regulations are unnecessary in a free economy, as inefficient monopolies by definition are vulnerable to competition, and efficient monopolies are already meeting their supply/demand ratio optimally.
Under the Antitrust laws, a man becomes a criminal from the moment he goes into business, no matter what he does. For instance, if he charges prices which some bureaucrats judge as too high, he can be prosecuted for monopoly or for a successful “intent to monopolize”; if he charges prices lower than those of his competitors, he can be prosecuted for “unfair competition” or “restraint of trade”; and if he charges the same prices as his competitors, he can be prosecuted for “collusion” or “conspiracy.”
