>The big economies of the eurozone have been in constant stagnation for the last 15 years.

Eurozone doesn't know how to manage the economy successfully. The euro has been a failure. We went from somewhat parity with the US in 2006 to lagging quite behind them 20 years later.

> the Euro has been a failure

My bank account disagrees.

I was referring to the caps being attached to bottles part.

Also, a strong currency does not equate to a strong or well-managed economy. (Unless you're Donald Trump.)
