Chapter 14- Supranational cooperation in the European Union
New countries might not want to join the EU because the economic process might not be worth the trouble. New countries would have to convert their entire economy to the Euro. The country could leave their currency the same, but they wouldn't be able to trade and work with the same ease as countries that have the Euro too. Some countries who want to join the EU might not be able to meet the economic standard that are required to switch to the Euro currency. Also, because of the Economic state of eastern Europe, citizens of eastern Europeans countries are willing to work for lower salaries than citizens of western European countries. For this reason, western Europeans countries that are not a part of the EU might be less inclined to join the EU, because they could lose their jobs.
It will be more difficult to communicate with the addition of more countries to the EU. When more countries are added to the EU, legal documents will have to be translated to even more languages and will increase the language barrier between countries in the EU. New countries will also be discouraged to join the EU because of their cultural traditions. Some aspects of a country's culture could be disapproved of or even illegal in the EU.
New countries might struggle to join the EU because they do not want to join a supranational cooperation. Their own country's national pride could make them hesitate to give up control over some of their own country's national independence. As more and more countries join the EU, it becomes harder for all the differing opinions to reach a compromise.
