Keynesianism and Stagflation

Keynes, with his heretical contribution to the family of the neo‐classics, was as profound as the heresies of Luther against the Pope. He accepted the institution of profit, private initiative, personal ownership of the means of production, the price mechanism of the market in the production and consumption of goods and distribution of income. He refused to accept, however, the old concept of equilibrium with full employment according to the Say law of the markets. Instead he introduced the concept of equilibrium with unemployment, anathema to the classics.
