There is an interesting history at work here. Though politically dynamic, the most interesting aspect of Russian Communism was the fact it was an economic theory that featured state-centred bureaucratic control of a national economy. This state-centred economic approach ultimately was the undoing of the system. Thus, with Russian Communism discredited and abandoned around the world, today's student radicals don't have an ideological centre. There is no other political way presently foreseeable for the assembled masses that have taken to North American streets over the past three years, except for the one they're protesting against.
Capitalism is ascendant.
The market rules. We're told that the market should decide not only the kind of cereal we select in the supermarket, but also the number of hospital beds and daycare places. The people in the streets in Washington D.C. and Seattle don't seem to think so. The protests against the IMF, APEC, WTO and the World Bank have an economic theme. All are strictly multinational economic associations.
