Keynes and the Ruling Class – Garet Garrett – Mises Daily.
The balanced budget was a capitalist bogey. Deficit spending was not what it seemed. It was in fact investment; and the use of it was to fill an investment void — a void created by the chronic and incorrigible propensity of people to save too much. “There has been,” he said, “a chronic tendency throughout history for the propensity to save to be stronger than the inducement to invest. The weakness of the inducement to invest has been at all times the key to the economic problem.” By investment he was supposed to mean the use of capital in the spirit of adventure.
This idea was the very base of the theory. From oversaving and underinvestment came unemployment. And when from this cause unemployment appeared, as it was bound to do, first periodically and then as a permanent evil, the only cure was for government to spend the money. Among the algebraic tools was the famous multiplier by use of which the experts would be able to determine precisely how much the government would have to spend to create full employment.
