Governments everywhere benefit from central (government) banking. Central banking allows governments to extend their alleged “benefits” without directly and immediately taxing their oppressed subjects. Essentially, governments are able to game a society’s cost/benefit analysis and appear more attractive.
But it is all a lie. Government deficit spending means that government currencies are constantly being debased.
Now, increasingly, government banks are setting “negative” interest rates: you pay the bank to keep your money, rather than the other way around. See here.
