Most EU countries have their own language which makes communication difficult between citizens within EU. If all countires had english as a 2nd language with their original primary language it would benefit everyone. Travelling around EU, finding jobs, diplomatic relations would benefit greatly from english being the language all knew. English is already very popular in the internet and it's the language for science.
In small countries like Finland and Scandinavia english is more important than Germany, France and Italy because they have large number of native speakers. It's a problem, Finnish people know english better than Italians partly because of necessity and education system.
So, I'd seriously want to see a future where english is an official 2nd language in every nation in EU. I'd want it to be taught as an important subject from young age everywhere. I feel the effect on economy and communication would greatly benefit from it happening. On this note I'd want to be able to speak with people from countires outside EU too, many Asian countries are off the radar for me because of the language barrier. So while unrealistic english being 2nd language in All countries in the world would be great.
Does anyone share my belief?
