Journalists love spectres, and the Occupy movement which has spread from Wall Street to Europe seems like the beginning of something fresh and ominous. Theres a lot of anger on the streets at the moment, one young man outside St Pauls Cathedral told the BBC. Given the paltry numbers, he wasnt sure it was going to change the world, but it was good and necessary to be there all the same. Im glad to be here, he said. Good for him. Any protest is better than nothing, but if theres one thing thats shocking about these demonstrations, its how weak and inarticulate they were. Fine to speak up against greedy bankers, but without any other political arguments who needs arguments when you have Facebook? it rather seems like youre damning the millions who lived off their loans in the first place. And why would they want to do that? As the fog of mainstream economics clears, it turns out that the growth miracle of the past few decades has been built less on new technology but on asking ordinary people to work harder and longer, and then take on part-time work to make ends meet. If the annual income of the median American household had continued to grow at its post-war rate, for example, it would now be over $90,000. But sometime in the last few decades it got stuck at a paltry $54,061. With real wages stagnant, ordinary people on both sides of the Atlantic are now being asked to tighten their belts even further at a time when theres little work to go around. If anything, its shocking how little anger there is on the streets. But maybe thats understandable, given the tenor of the protests. Its lovely to imagine a world without greed, but no one ever built a movement without appealing to the real interests of ordinary people. Its not hard to think of what those interests might be. Financial re-engineering, fictitious profits, inflated home prices; our economic managers had been living beyond their means, kept afloat on a line of cheap Chinese credit because the rate at which our economies had been growing jobs and productivity had been slowing for decades. The banks were only the beginning of it. Unless these new anti-capitalists find a way to hitch their demands to the interests of the rest of the population the 99 per cent they claim to speak for theyre stuck in a self-righteous bubble. And until they do so, their tirades against greed reek of the worst kind of Victorian self-righteous puritanism. It used to be that workers occupied factories, but now these sons and daughters of the bourgeoisie have seen fit to occupy the space outside a church. If theres a spectre haunting capitalism today, its nothing more than its own self-loathing. James Harkin is the author of 'Niche: Why the market no longer favours the mainstream The Independent
