It is interesting to note that in nearly all the economics courses it is taught that the income tax is the proper instrument for the regulation of the country's economy; that private property is not an inalienable right (in fact, there are no inalienable rights); that the economic ills of the country are traceable to the remnants of free enterprise; that the economy of the nation can be sound only when the government manages prices, controls wages, and regulates operations. This was not taught in the colleges before 1913.
