And in France working class politics are in the ascendancy? There are differences between the situation there and in the UK, to be sure, but what you hear seems to mostly more of the same old same old.
As for Eastern Europe, it will take a very long time to repair the damage done to the name of any politics that have the working class interest at heart by the old ruling ideologies. For example, 'the masses' were on the streets in enormous numbers quite recently in Ukraine, were they not? Any enthusiasm for those they were there in support of? No, me neither. But I bet they dwarfed the crowds at any anarchist or left event.
