Fascinating! So it turns out that we agree!
CBs set interest rates low to rescue the Banks after the collapse of 2008. It is definitely an transfer from savers to Banks. Since the banks didn’t have enough capital, it was the only thing left to do, unless the CBs were prepared to take the banks into public ownership. The combination of unwillingness to nationalize weak banks but desire to pretend they were solvent is why rates had to be cut to zero.
However the design of the system requires CBs to have the power to set rates.
If capitalism is to be anything other than a system of entrenched privilege it must be possible to fail. CBs effectively ended capitalism in 2008 - creating a system of socialism for the rich, atty the expense of the rest of us.
I would say lynch them, but remember that it was not the Central bankers that made the decision but Obama.
