Noam Chomsky is taken seriously, even in the USA, to say nothing of the rest of the world, probably much more so than any of the French intellectuals who have made the front page of Le Monde. So are many other American intellectuals on the Left, like Ralph Nader, Michael Moore, the late and lamented Edward Said, the late and lamented Stephen Jay Gould, etc. What makes American intellectuals different from those of the rest of the world is that in America intellectuals, when they get taken seriously, become individually famous and acquire individual followings, and their sayings and doings, however correct, do not help build enduring popular movements and institutions, especially political parties.
In other words, American intellectuals are the antithesis of "organic intellectuals" as defined by Gramsci:
The working class, like the bourgeoisie before it,
is capable of developing from within its ranks
its own organic intellectuals, and the function of
the political party, whether mass or vanguard,
is that of channelling the activity of these organic intellectuals
and providing a link between the class and certain sections
of the traditional intelligentsia. The organic intellectuals of
the working class are defined on the one hand by their role
in production and in the organisation of work and on the other
by their "directive" political role, focused on the Party.
It is through this assumption of conscious responsibility,
aided by absorption of ideas and personnel from
the more advanced bourgeois intellectual strata,
that the proletariat can escape from defensive corporatism
and economism and advance towards hegemony
