Marxism grows among clueless people that are living in either restricted and nontransparent societies including Iran, Cuba and N.Korea or on university campuses. Just like STD, it is mainly alive among the young people.
But for one thing it can be a bit different in Iran: The article appeared in Int'l Herald Tribune or NYT about the growth of Marxism in Iran makes me believe that the evil Mullahs have set these clueless Commies up to battle the influence of the westernized political activists and pro-US students. However, Soviet Union doesn't exist any more to back these idiots up in their quest to take over the country and the rest of the Commie-fested countries have now become the mullahs' best friends. It's a matter of time, age and maturity for these clueless crowd to find its way out, although it is troubling and makes the true opposition more responsible in trying to educate them about the benefits of free market, private enterprise and freedom of choice... etc. It'll definitely help if some body asked them to name one successful Communist country.
Is any Milton Friedman's book available in Iran?(Wikipedia on Friedman)
