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.

A tight ECB policy wouldn't permit that to happen again.

We had much freer trade in the 19th century. We have much less globalization now than we did then.

In response to a suggestion that total free trade would end in cheaper foreign products flooding the market and causing unemployment.

I am myself persuaded, on the basis of extensive study of the historical evidence, that... the severity of each of the contractions - 1920-21, 1929-33, and 1937-38 - is directly attributable to acts of commission and omission by the Reserve authorities and would not have occurred under earlier monetary and banking arrangements.

The only reason there is a crisis about Social Security in the US and pensions in Europe and Japan is that you cannot maintain a "Ponzi" scheme indefinitely.
