While your busy doing that, i agreed fully with the common market, but like many, not into how this as morphed into a political union......
But it hasn't morphed into a political union, it was always intended to be one. National politicians across Europe could not face selling such an idea to the voters and have therefore always referred to the economic framework and its advantages or disadvantages as if that was the sole aim. Even the phrase "common market" was invented by our own politicians to avoid referring to the EEC, EC or EU.
The glue and/or the incentive for European political union is economic integration of the member states. On that front, there is no doubt that our economic position today is comparatively healthy and continuing to improve.
While on the political front, there is no doubt that we will retain greater political influence if we can retain EU membership so that we can increase our influence through Brussels. (And if we don't, Germany will).
