re: Can anyone explain to me why the entire world banking system

We want to allow Central Banks to:
a)Have fractional reserve banking i.e. banks can lending money they don't have
b)Have quantitative easing i.e. counterfeiting or the artificial printing of money
c)To repress the amount of interest rates i.e. so we don't have the real cost of money
d)Have deposit guarantees i.e. so when the bank goes broke; the taxpayer picks up the tab
