I wished I had listened to my father when I was younger. A thoussand dollars a year for 40 years at 10% interest will be a million dollars. I wasted so much money when I was young.
The stock market has gone nowhere for the last 5 years despite a 50% debasement of the money supply; interest rates are below the true rate of inflation.
Where are you going to find 10% a year for 40 years?
