We now have a global business system that is virtually unregulated, with trade unions crippled and politicians largely bought by the super-rich to serve their interests. And what is the result? Inequality has returned to 1920s levels, and movement between the classes has collapsed. We have bank runs unseen in a century. And now even senior Wall Street figures mutter - with only a hint of hyperbole - about a looming Depression and "the worst crisis since 1929." All we need now is rising unemployment and Zelda and F Scott Fitzgerald boozily waltzing through Wall Street, and we are back where this story began.
