Give one benefit of the European Union or the Arab Common Market

One benefit of the European Union common market is that it allows the free flow of goods, services, people and capital among member nations.

Explanation:

This free movement for example allows a citizen from Spain to work at a company in France with the only requirement of being hired by the company. It also makes the capital markets in Europe more dynamic because funds flow freely among more than 28 nations. Finally, European consumers benefit from higher quality and cheaper goods and services thanks to the increased competition that the free flow of goods and services brings about.
