Seventy-three years ago, John Maynard Keynes thought about the reform and regulation of financial markets from the perspective of the first three purposes and found himself “moved toward... mak[ing] the purchase of an investment permanent and indissoluble, like marriage...” But he immediately drew back: the fact “that each individual investor flatters himself that his commitment is ‘liquid’ (though this cannot be true for all investors collectively) calms his nerves and makes him much more willing to run a risk...”
73年之前，约翰·梅纳德·凯恩斯在对金融市场的改革和监管时候，提及关于最初提到的三个目的时候说，他的目的是使得“他的投资购买行为转向成永久的和不可分割的，就是婚姻那样。”但他立刻说明一个事实“每一个投资者都欺骗自己说他们的资产是可流动的（虽然如果所有投资者想要变现的话，资产就不可能变现。）有了这样的前提，他们就可以放心来进行更为大胆的冒险行为。”
