Large Argi-Businesses are no different than Soviet-style Kolkhozes.
The kohlhozes are in turn similar to the large landed estates owned by the European aristocracy in the Middle Ages.

It is not Austrian economics, but antitrust laws serve a purpose of preventing the concentration of economic power, which in turn influences political power.
