Bankers should automatically forfeit 99% of their wealth. The owners like the Rothschilds can forfeit 99.999999%. Audit them and then pay off all debts with their wealth - which they stole. You'd have money left for infrastructure projects, sending humans to Mars and beyond, beautifying the world etc.
1/1,000,000 x 500(1,000)(1,000)(1,000,000) = 500,000,000 = 500 million dollars or 1/millionth left of their wealth. Still generous by any standards.
