It's somewhat disingenuous to claim Germany as an example of "balance" when Germany's ascent as the dominant European economy was accomplished by chaining the less productive members to become the spokes to Germany's wheel.
Pretty sure that some in this thread quoted the existence of the French welfare state before the EC and EU as proof that the French model is viable. Well, so I claim the same for Germany then.
And if you don't like the German example, take Switzerland which doesn't even need that sort of 'manipulation'.
I know you didn't even name it, nevertheless I can also adress another elephant in the room: 'German currency manipulation', by which I simply mean the bizarre fact that Greece and Germany are supposed to be largely the same economy due to having the exact same currency including the same central bank.
I very much agree that this is just bullshit and that anyone in €-land who isn't Germany suffers from it (except maybe Austria, the Netherlands, even Finland struggles). But it's just a historical fact that it was exactly France that wanted to share Germany's currency in exchange for allowing German reunification. If the idea there was indeed to secure Germany not outperforming France, Italy or any 'soft' currency holder prior to the €, this obviously backfired spectacularly. But still, neither German government nor the German electorate wanted this particular detail, that's on you France.
