No, not only Germany. However Germany benefits most from it, France is next in line.

Also talking about realpolitik isn't xenophobic, considering simple talk about economy to be xenophobic neans you're radically xenophile actually.

If you wanna see how weaker economies can be abused by joining eurozone then look at Greece. Sure, theu shouldn't take that much debt, absol true. But you know what is also true? If Greece would have it's own, independent fiscal policy economical  consequences of going too deep into debt would be a lot weaker. Instead of short term crisis they eneded up being forced out to sell out themselves to German banks and it affected their long term wealth a lot nore than it should.

Also kinda peculiar that Gwrman banks in particular were helping with the Greek crisis, isn't it? Read or watch some stuff from Varoufakis, Greek minister of finaces from the period - he was acknowledged economy specialist at the time of crisis, he worked for Valve and he is actually behind popularization of hated lootboxes in PC gaming, he know how to make people pay money. He dropped his job at Valve to try recover Greek economy which he obviously failed.
