J Asmussen, member of the executive board of the ECB and ex-Deputy Finance Minister of Germany, was roped in to endorse the idea. He liked it but added that the additional pot of subsidies alone would hardly be enough for the euro to make it to 2025. The Eurozone cannot function the way it has been conceptualized, he admitted. That's why we have to systematically develop it further over the next few years Hence total integration. The Banking Union would just be the next step, he said.
And so the McKinsey study and Asmussen agreed: total Eurozone integration would be required for the euro to make it; and the euro would be required for Germany to reach the Golden Twenties and experience a second Economic Miracle.
