In other words, such a world needed either the reality or the illusion that finance could, as John Maynard Keynes put it, “defeat the dark forces of time and ignorance which envelop our future.” Most reforms that would guard against macroeconomic risk would also limit the ability of finance to persuade people to commit to long-term risky investments, and hence further lower the supply of finance willing to assume such undertakings.
换句话说，这样一个世界需要一种现实或者幻觉——金融能像凯恩斯所说的那样“击败困扰着我们的未来的时间和无知的黑暗力量。”大部分预防宏观经济风险的改革也会限制金融说服人们进行长期风险投资的能力，从而进一步减少了愿意这样做的金融供给。
