There's a thought-provoking new article by Chris Bambery on the website of Scotland's International Socialist Group. His starting point is this:
'One notable feature of recent global resistance to austerity is the absence of the Left. There have been momentous strikes and protests across Europe, the Arab world, and even America as governments make the poor pay for the economic crisis with cuts, unemployment, and wage crunches. This will certainly continue. The capitalist system, as Marx pointed out, breeds class struggle. But this does not guarantee that the Left will respond effectively to grow its influence and membership. Resistance doesn’t necessarily build the infrastructure of the Left.'
