Beware all vanguards!
Way back in the midst of time (or the mid 19th century to be precise) was an organisation called the first International Working Mens Association - or First International for short, which declared that "the emancipation of the working class is the task of the workers themselves". We would do well to remember those words as we struggle against austerity, as there's no shortage of would-be vanguards vying to substitute themselves for mass collective action.
