The bank cartels probably won't last long, just wait until money becomes mostly decentralized and digitalized. We'll finally be able to use our money without limits or immoral intermediaries.
Example is Lebanon where if you send someone US Dollars, they’ll receive it in the local currency which is under hyperinflation.
The central bank governor (government too) there is pure evil and is a US political pawn. I know it sounds outlandish, but if you look into it, you almost wont believe its real.
