Very quickly off the top of my head, we've had the savings and loan crisis of the 80-90s, Black Wednesday in '92, the Great Financial Crisis, and the European sovereign debt crisis. I don't think the world can handle any more competency in central banking.

Not if you measure competence in terms of how much value the USD lost over the past 50 years vs the 50 years before that.

The first 30 of the past 50 years you mean.
