Banker - 1600 A.D.
Before John Calvin people were not allowed to lend money at interest.
John Calvin decided to legalize money-lending at interest in spite of the teachings of the Prophets of Israel and the Fathers of the Church.
Protestant countries tried to keep up with John Calvin and money-lending at interest became the general practice.
And money ceased to be a means of exchange and began to be a means to make money.
So people lent money on time and started to think of time in terms of money and said to each other: “Time is money.”
