"U.S. companies earn more from their investments in the EU than in the rest of the world combined"

This quote by John Bruton suggests that U.S. business are more successful in their investments in the European Union than in any other area of the world. This might be due to the fact that the EU is a large and prosperous market, with a population of over 500 million people and a GDP of over $17 trillion. The EU also has a strong regulative structure and a single market, that makes it easier for U.S. business to do company in the region. Furthermore, the EU has a number of open market arrangements with other nations, which can assist U.S. business to access new markets and increase their profits. For that reason, it is not unexpected that U.S. business are making more from their investments in the EU than in the remainder of the world combined.
