As a postscript to this chapter I should add that its argument is not directed against all tariffs, including duties collected mainly for revenue, or to keep alive industries needed for war; nor is it directed against all arguments for tariffs. It is merely directed against the fallacy that a tariff on net balance “provides employment,” “raises wages,” or “protects the American standard of living.” It does none of these things; and so far as wages and the standard of living are concerned, it does the precise opposite.
