It is the crazy dynamics of global capitalism that make effective resistance to it so difficult and frustrating. Recall the great wave of protests that spilled all over Europe in 2011, from Greece and Spain to London and Paris. Even if there was no consistent political platform mobilising the protesters, the protests functioned as part of a large-scale educational process: the protesters’ misery and discontent were transformed into a great collective act of mobilisation – hundreds of thousands gathered in public squares, proclaiming that they had enough, that things could not go on like that. However, what these protests add up to is a purely negative gesture of angry rejection and an equally abstract demand for justice, lacking the ability to translate this demand into a concrete political programme.
tl;dr: Occupy Wall Street was a way to loudly proclaim that people were fed up, but unlike the Tea Party, was too unfocused to translate the momentum into a coherent political position.
Any ways, long, but good read.
