Thanks in part to the grip of corporate power on the media and on political parties, few today in the West can imagine any other politics than those of big money. In the US, and increasingly even in Europe, the income differential between the poor and the wealthy already resembles that of banana republics. The downtrodden are asked to bear the burden of a financial crisis created by bankers. America's wealthy fly their children to summer camp in tax-free private jets amid a real rate of unemployment of over fifteen per cent.
Neoliberalism has only accelerated these processes at the heart of capitalist society. Here is a far more convincing threat to Western values and "social cohesion" than the lunatic fears of fascists. Notably, this is a threat that emanates from within, not without. It is precisely social democratic parties like Norway's Labour Party - Breivik's target - which have sought to contain the corrosive effects of capitalism and ensure the survival of the West's most humane values.
Multiculturalism does not pose a significant danger to Western values - but neoliberalism does.
