In the formalised study of politics, it is more than 300 years old, having been articulated with great care by John Locke in the late 17th century. The modern study of economics is well over 200 years old. Adam Smith’s Wealth Of Nations was published in 1776 - the same year as Thomas Jefferson’s Declaration Of Independence. The great work which finally integrated money with politics and economics celebrates its centennial this year. Ludwig von Mises published his Theory Of Money And Credit in 1912 - the year before the US inaugurated an income tax and a central bank. Ten years after that in 1922, von Mises published Socialism - a book which established beyond refutation the fundamental truth that any form of central planning and/or government control of the means of production cannot work because it makes economic calculation impossible.
