Any guesses about how much interest on loans they've made since 1913?

I think what's most disturbing now is they really are just typing money into existence now via credit loans with the added economics of oligarchy which is vacuuming up most of the money that does exist into the hands of the 1% which makes the masses desperate for that loan at interest credit money.
Anything good going on in the world right now will eventually become null and voided by this issue if someone doesn't put a stop to it.
