I would rather say that most euro countries are being ripped of by Germany, in multiple ways like the beggar thy neighbor of internal devaluation, rigid finacial policy when it suits them, way too higher trade imbalances with the other euro area countries, etc ... but is way cooler to say that "they are paying", because they are germans, right ...
[missing reference] I see this thrown around often, but have never found any references which take into account the trade balances, respective debts, tax contributions, etc.
