The Myth of Monopolies and Market Concentration

Professor Thomas DiLorenzo has a major contribution to your education:

the Sherman Act was a tool used to regulate some of the most competitive industries in America,which were rapidly expanding their output and reducing their prices, much to the dismay of their less efficient (but politically influential) competitors. The Sherman Act, moreover, was used as a political fig leaf to shield the real cause of monopoly in the late 1880s-protectionism. The chief sponsor of the 1890 tariff bill, passed just three months after the Sherman Act, was none other than Sen. Sherman himself.

The rent-seeking hall of fame.
