把这一句，留给此刻的你
It is not a correct deduction from the Principles of Economics that enlightened self-interest always operates in the public interest... Experience does not show that individuals when they make up a social unit are always less clear-sighted than when they act separately.
从经济学原理中推断，开明的利己主义总是为公共利益服务，这是不对的。经验并不表明，当一个人组成一个社会单位时，他总是比单独行动时看得更清楚。
