What central banks can control is a base and one way they can control the base is via manipulating a particular interest rate, such as a Federal Funds rate, the overnight rate at which banks lend to one another. But they use that control to control what happens to the quantity of money. There is no disagreement.

Everywhere, and at all times, economic progress has meant far more to the poor than to the rich.

Every friend of freedom... must be as revolted as I am by the prospect of turning the United States into an armed camp, by the vision of jails filled with casual drug users and of an army of enforcers empowered to invade the liberty of citizens on slight evidence.

Italy may well be the main problem. It has benefited most from the euro by having been able to get the euro interest rate instead of what otherwise would have been its own. That would be much higher because Italy has been accumulating so much debt. In the past, Italy has inflated away its debt. The virtue of the euro is that Italy can't do it alone. A tight ECB policy wouldn't permit that to happen again.
