Individualist, as distinct from socialist, anarchism has been particularly strong in the USA from the time of Josiah Warren (1798-1874) onwards and is expressed today by Murray Rothbard and the school of 'anarcho-capitalists'.
There are anarchists of the right such as Murray Rothbard ( For a New Liberty [New York: Macmillan, 1973]) who defend private property and free enterprise.
The Anarcho-Capitalists, who had more of a historical sense, did occasionally cite past anarchists like Spooner and Tucker as "the forefathers of modern libertarianism," but only a few individuals like Murray Rothbard, in Power and Market , and some article writers were influenced by these men. Most had not evolved consciously from this tradition; they had been a rather automatic product of the American environment.
Largely due to the path breaking work of Murray Rothbard, 20th century individualist anarchism is no longer inherently suspicious of profit-making practices, such as charging interest. Indeed, it embraces the free market as the voluntary vehicle of economic exchange. But as individualist anarchism draws increasingly upon the work of Austrian economists such as Mises and Hayek, it draws increasingly farther away from left anarchism.
