Is a good assumption that money created by private banks more stable than government created money? what economic mechanism provides such guarantee and what is the evidence?
Private banks used to be able to print their own currency completely: in one country each bank would have different money that coupd be redeemed for gold, and wasn't backed by the government. That was very unstable.
We basically stopped taxing multinationals after the end of cold war, we do have something new.
