As a shell-shocked world tries to fathom how its economic collapse happened, commentators are busily outbidding each other with claims about the exceptional nature of this crisis. But the most astounding fact is how familiar its physiognomy and physiology look compared to past financial crashes.

No one can read the chronicles of those earlier crashes without sensing – with a chill – that history is repeating itself. The story of the modern capitalist economy is a rhythmic repetition of cycles, syncopated by eerily similar crises. These crises, while their details differ, are but variations on the same theme. Easy money, geared up by leverage, floods the financial system through innovative products. This simultaneously pumps up asset prices and obscures their speculative nature, with euphoria usurping the place of analysis. Until, one day, something triggers a loss of confidence in the continued rise of prices, and the whole leveraged edifice crumbles.
