Trouble is staying in will not be the 'status quo' and thats the single biggest misconception. With Albania and Turkey and other countries poised to join the EU even as we know it today it will change.
Turkey won't join. They won't even come close.
Turkey are far away from even meeting the EU requirements to gain visa-free travel for temporary stays (which, by the way, is in the Schengen Area only, which we are not a part of).
On the 33 chapters of EU legislation to actually join the EU, Turkey are miles away when it comes to certain chapters, especially those involving human rights and press freedom.
Davutoglu, the pro-EU Prime Minister who has been pushing towards EU membership, is also set to resign shortly, leaving Erdogan to continue to increase his grip on power and undermine human rights.
Only this month, Erdogan has refused to change the laws required for visa-free travel, and said to the EU, and I quote, "We'll go our way, you go yours".
Then you have the situation regarding how EU membership is granted. All member states must vote unanimously in favour of a new EU member before they can join, meaning that only a single member can veto the entire thing.
Germany has long been an opponent of Turkey's membership, and Turkey continues to refuse to recognise the Republic of Cyprus as a nation. The vast majority of the public across the EU are also not in favour.
When it comes to Albania, they are much further behind than even Turkey in meeting all the necessary chapters for EU membership. It will be at least another 10-15 years before they're even close.
However, with a population of only 2.8million and a high Human Development Index, along with universal healthcare, free education and a respectable mid-level economy, any effects of their membership are likely to be strongly overstated.
Believe it or not, there aren't many people out there in rather comfortable countries who are eager to quit their jobs, pack their bags, leave their friends, leave their family, take their comparatively little money and move to an alien country with a completely different language and culture. The cost of living in Albania is considerably less than it is in other EU countries. It's all relative.
Interestingly, the number of Poles living elsewhere in the EU peaked around 2007, and has since actually
gone down. That's right. Many immigrants from "poorer" countries have moved abroad to places like the UK, Italy and Germany, and then decided to return back home.
