While right-libertarianism refers to "laissez-faire" capitalism such as Murray Rothbard's anarcho-capitalism and Robert Nozick's minarchism, socialist libertarianism "viewany concentration of power into the hands of a few (whether politically or economically) as antithetical to freedom and thus advocate for the simultaneous abolition of both government "and" capitalism." According to Jennifer Carlson, right-libertarianism is the dominant form of libertarianism in the United States while left-libertarianism "has become a more predominant aspect of politics in western European democracies over the past three decades." Socialist libertarianism has been included within a broad left-libertarianism in its original meaning. Left-libertarianism also includes "the decentralist who wishes to limit and devolve State power, to the syndicalist who wants to abolish it altogether. It can even encompass the Fabians and the social democrats who wish to socialize the economy but who still see a limited role for the State."
