Germany would love to devalue the Euro, for the same reason basically every country is trying to devalue their currency (US, China, Brazil, etc). They all think it will help their manufacturing sectors by increasing outputs. Unfortunately, not all currencies can simultaneously devalue.

Relative to other currencies, sure, but within the EU (and any euro-based market) more euros would decrease buying power & devalue the debt (much of which Germany owns). Neither of those effects are beneficial to them.

But in total, it would be beneficial. Probably not popular due to the irrational fear of hyperinflation that is prevalent in Germany for historical reasons, but beneficial.
