It was simple to begin with, it has now morphed into a giant undemocratic political monster with trade merely a by-product
Hence a servile position
Sorry, I do not think the Common Market or EC or EA has EVER been simple.....
before we joined there was considerable disagreement and self-service being operated by member countries - that continues to the present day, only there are now more of them doing that (including the UK).
Originally De Gaulle and his repeated "Non" was because he KNEW the CAP was fundamentally to support inefficient French farmers - and that has not changed, neither has the CAP been reviewed - because France has still vetoed any such discussion.
Spain has taken a similar stance over the CFP - since the Spanish fishing fleet is so much larger than others, and they will not accept any major shifts in how it functions to support Spanish registered boats.
Greece? Enough said.....
The "New" members have joined partially for trade access but more importantly for the subsidies they will receive under various parts of the various treaties - but Cornwall has similarly benefited from such subsidies - although the UK Government s now trying to reclaim them from the bodies in receipt for various trivial reasons - like the organisation did not get the matched funding from the UK Government and therefore should return to the UK Government the money that was received from Europe......
But such ridiculous things can and will only be changed from inside and frankly Cameron was pushed into high speed negotiations which have not addressed the fundamental flaws - that I agree with.
But such flaws will NEVER be tackled from outside - there is no mechanism for such to happen as Norway says repeatedly.
The EC needs massive changes and needs these rapidly - so the diversions of a Brexit vote have hampered, not helped, such changes even being debated......
Stay in, keep talking and keep pointing out the errors and keep blocking changes that take the EU further down the wrong route.
Britain has got Europe out of trouble twice in the last 100 years - this is a different battle but the outcome will be the same, we ALL move forward together.
