  • 23. Keynes‟ Open Letter to President Roosevelt… “Thus, as the prime mover in the first stage of thetechnique of recovery, I lay overwhelming emphasis on theincrease of national purchasing power resultingfrom governmental expenditure which is financedby loans and is not merely a transfer through taxationfrom existing incomes.”
