Re: Did UK make ever something positive to make EU stronger?
For the Euro, as a European citizen, I enjoy having the same currency than our neighbors: no more banks taking their parts when converting money, no more harsh conversion to calculate the price of an item, no more unchangeable coins when getting back home...
"Lets all be in a currency union because it makes it easier to buy things when travelling" is a ridiculous argument because it ignores the fact that currency union implies a lack of control over the levers of the economy, like currency and interest rates. See how Spain, Greece and Portugal have faired when they are forced to operate within what German industry wants. It is utterly simplistic and childish to think of the Eurozone in terms of buying pizza and beer on holiday.
Similarly, Schengen makes absolutely no sense for UK travellers, it's a big fucking island. You will be checked coming in by boat, plane or train regardless of UK's participation in Schengen, the current border controls being a minuscule part of that process. There is no facility gained in our participation.
A vote to "Remain" is not a vote to join either of those two barmy schemes, whilst voting to "Leave" will have us at best end up in EFTA with FSM knows what tariffs on our goods and services. Norway is a member of EFTA, they have to obey all the EU rules and regulations with no say on how they are implemented, and they still have massive tariffs on one of their largest exports (fisheries), are required to be in Schengen and have free movement of people.
Friday cannot arrive quick enough, thoroughly sick of all this.
