Libertarianism is a name for the political views of everyone who is fiscally conservative and socially tolerant. Libertarians favor increases in both economic and personal liberty.
Libertarianism is different from both modern conservatism and modern liberalism.
While many conservatives share the libertarian's skepticism of government in general, modern conservatives tend to favor using the criminal justice system to promote traditional moral values. The Reason Foundation has also sponsored studies on the privatization of various government services. Other books provide a more general introduction to libertarian ideas. It was also made into a multi-episode PBS documentary. The Friedmans are strongly libertarian, favoring much less government across the board.
