Economist article asks if this is a good thing. An excerpt below:
Mandating English might also serve to undermine loyalty to the EU. There are too many Europeans who would rather not have English dominate political affairs. The continent has more native German-speakers, including four countries where German is an official language. French has as many native-speakers in Europe, too, and is official in three countries (not to mention Europe’s de facto capital, Brussels). Native English-speakers make up less than a fifth of the EU’s population. And, awkwardly, English is the official language of the one country that will soon hold a referendum on whether to quit the EU entirely.One of the joys of traveling is hearing different languages, and learning how to communicate in new ways. It is definitely more challenging navigating through Italy than it is through Orlando. The cultural experience of traveling leaves such a strong imprint, and different languages are a big part of that.
