No offence but that was a little simplistic and condemnatory.
If you included the entire paragraph it would have answered your quiry:
Chomsky is often described as one of the best-known figures of the American Left, although he doesn't agree with the usage of the term. He has described himself as a "fellow traveller" to the anarchist tradition, and refers to himself as a libertarian socialist, a political philosophy he summarizes as challenging all forms of authority and attempting to eliminate them if they are unjustified for which the burden of proof is solely upon those who attempt to exert power. He identifies with the labor-oriented anarcho-syndicalist current of anarchism in particular cases, and is a member of the Industrial Workers of the World. He also exhibits some favor for the libertarian socialist vision of participatory economics,[2] himself being a member of the Interim Committee for the International Organization for a Participatory Society.[3]
He believes that libertarian socialist values exemplify the rational and morally consistent extension of original unreconstructed classical liberal and radical humanist ideas in an industrial context.[4]
Obviously, puts his time into action with various organizations that I think you would agree would help put back some of the balance regarding labor rights and participation in peoples lives in a more livable society.
