Come on! Everybody knows the EU is keen on centralizing, it might be that because you're from already very centralized France that you don't notice this, but that's the way it is. Taxes? I heard in another thread that 0.25 per cent (IIRC) of the British budget goes to the EU. That's money which Britons have payed in taxes to the EU. It's small, but it is still tax money. Besides the EU often talk about the importance of "tax harmonization", which always mean taxes are going to be raised.
