Where did banking, business, and usury begin according to this teaching?

Les explains that if you know anything about history, banking and business, and spending or using money for usury, began with Babylon. Babylon was the first empire that began to promote banking and business in that way, and that is why the Jews settled down so quickly in Babylon. He then notes that the Medes and Persians came next, and many of their attributes are still with us today, though they are not as evident as the Babylonian or Greek. Much of Greek culture, Rome was careful not to destroy because it was profitable to integrate into its own empire. This fits the larger flow of the Gentile system preparing for its demise at the Second Coming of Christ, with the revived Roman Empire containing remains of previous empires.
