Once it is realized that business monopoly in America paralyzes the system of free enterprise on which it is grafted, and is as fatal to those who manipulate it as to the people who suffer beneath its impositions, action by the government to eliminate these artificial restraints will be welcomed by industry throughout the nation.
For idle factories and idle workers profit no man.

Franklin Delano Roosevelt (1882–1945) American lawyer, politician, statesman, US President (1933–1945)

Message (1938-04-29) to Congress, On Curbing Monopolies
