>"why are central bankers "necessary"

I didn't say they were, though I much prefer a system with them included.

I said "banksters" are necessary. You know, in the same sense garbage collectors and lawyers and doctors and teachers are necessary. I mean, I guess you could argue that none are really necessary. But again, as a bank customer and user of credit (which I'm sure you and 95% of everyone else here is), I will call them necessary for my desired society.
