the article doesn't get the point, though, that if they want any long term success then the masses of people should be focusing on building new economic relationships, seizing productive capacities for the people, etc rather than recreating the perpetual disappointment and failure that is parliamentary democracy.

the better conclusion is that movements must be spontaneous, focused on changing living conditions outside of government structures and constantly vigilant against co-option from political forces. there was a critical mass assembled in egypt. had they stormed the factories and the fields instead of the parliament, they might have actually accomplished something.
