Not ancient Babylon in Iraq. Rather, Babylon in Revelation in the Bible, where the money system drags people into slavery.
11“The merchants of the earth will weep and mourn over her because no one buys their cargoes anymore— 12cargoes of gold, silver, precious stones and pearls; fine linen, purple, silk and scarlet cloth; every sort of citron wood, and articles of every kind made of ivory, costly wood, bronze, iron and marble; 13cargoes of cinnamon and spice, of incense, myrrh and frankincense, of wine and olive oil, of fine flour and wheat; cattle and sheep; horses and carriages; and human beings sold as slaves.
Iraq's ancient Babylon did the same thing. They did it through idolatry against God, and through astrology. The infamous 666 number has to do with several things. One of them is the angle of inclination of the Tower of Babel's walls, 66.6 degrees, built to worship the stars of the zodiac.
Today's idolatry is the worship of money, but in high levels of wealth, it is often still astrology.
