MOST people, including even trained economists, fail to appreciate the fact that an exchange rate depreciation, if it is to work in reducing the trade deficit in a capitalist economy, must necessarily hurt the working class by lowering the real wage rate. A capitalist economy, looking at it differently, improves its trade balance, for which it must improve its competitiveness, by lowering the real wage rate; and an exchange rate depreciation is one way of doing so.Most textbooks in economics do not mention this fact.
