That leaves the hope that a Tobin tax would induce high-IQ financial traders to do something else, with higher net benefits to society. If trading today is not helping to move capital to its highest and best use, reallocating inefficiently employed financial talent could yield big benefits.
最后是托宾税是否能促使高智商金融交易者转行，从而为社会创造净福利。如果今天的交易行为并没有让资本流向用处最大的地方，那么对未被有效利用的金融人才给予重新配置能产生相当大的好处。但是，交易过多真的是关键性的经济问题吗？
