Consider this passage from The Wisdom of Henry Hazlitt, newly online:
John Maynard Keynes was, basically, an inflationist. This has not been clearly recognized because he never spelled out, step by step, the consequences of his proposed remedy for unemployment and depression. That remedy was deficit spending by the government. He recognized that increased government spending paid for by equally increased taxation would not “add purchasing power.” The increased taxation would offset any “stimulus” that the increased government spending would provide. What counted, he confessed, was the government deficit.
But he failed to take his readers beyond this step. How would that deficit be financed? Either the money would have to be borrowed, or new (paper) money or credit would have to be created. But if the money were borrowed, then the previous spending stimulus would be reversed by a deflation when the borrowing was repaid. The only thing to prevent this reversal would be to allow the new spending to remain outstanding. In other words, the Keynesian solution to every slow-down in business or rise in unemployment was still another dose of inflation.
I may point out (if that is still deemed necessary in this inflationary era) that no inflation of which we have historical knowledge resulted in sound and continued business expansion but only in currency depreciation, a wanton redistribution of profits and losses, disorganized output, and economic demoralization. This has been true whether we begin with the coinage debasement of ancient Rome or the paper money scheme of John Law in 1716.
The lessons of inflation are soon forgotten. They apparently must be relearned in every generation.
