The response by the authorities to the Great Crash of 1929 was small and slow, and the world economy entered a “Dark Age” that lasted through the Great Depression of the 1930s and the Second World War. The 2007-2009 financial crisis portended a similar outcome, but this time the world’s governments and central banks intervened promptly, in a coordinated fashion, and with an appropriately high volume of stimulus.
而经济上的传染病就跟医学上的一样，都需要迅速果断的应对。当年各国政府在1929年的“大暴跌”中出手既慢又小，结果世界随之堕入了一个从1930年代“大萧条”延续到二战的“黑暗时代”。2007~2009年的金融危机本也预示着类似的后果，但这次全球政府和央行都联合起来果断出手干预，拿出了规模足够大的刺激政策。虽然复苏依然疲软，但总不会让我们陷入另一个“黑暗时代”。
