> There were always going to be weaker players in the EU

This is true, however there were quite strict criteria (the Maastricht criteria) put in place to try and prevent this from being too bigger problem. In hindsight, those criteria weren't sufficient, in one way or another.

I believe it's correct to say those weaker economies benefited from adopting the Euro the short term, and that they wanted to join the Euro.

As a twist, the Euro was somewhat unpopular in Germany when it was introduced, because it made things more expensive. So there is a feeling that Germany "paid" the price of adopting the Euro - whether this is true or not is irrelevant for the sake of policy-making.
