What are advantages of joining the EU for the EU?

Good Things about being in the EU
If your country is an EU member, you can buy something in another EU member for the same price as you'd buy the same good in your home country. With only a few exceptions, all of the members use the same currency, which would save time as you don't have to convert currency every time you to another member country. Also, border control is much easier when you travel within members. There is no more war in those countries against another member- in fact, when another member is in need, the rest of the EU will be there to support them. The EU makes its countries stronger and more united and gives them more democracy and a higher chance to have their voice heard. All of the EU countries will be able to take part in world decisions now, without being pushed aside by the US or China or another country with a big population. On that note, teamwork is essential to keep a union this big. If a criminal runs from one member to another to attempt an escape, he'll still be caught. Medicine aid in another member is the same price as it is in yours, and countries export their goods their rich in to countries where there poor in that good. One can safely say that the EU builds a safer environment not only in each member, but between each member as well.
