There are things that I don't like about the EU. Especially:
* Bureaucracy
* They spent 40% of their budget for agriculture subsidies.
* Now we have open boarders for immigrants from very violent and tribal societies. (You can downvote me for this if you like).
But here are many positive things. Freedom of movement. You can work, retire or open a business in any EU country that you want. Open skies - very cheap airfares (which will hurt the UK a lot).
What happens just this year is mind blowing.
* Free trade agreement with Japan
* Potential free trade agreement with Mercosur countries
* No roaming charges for cell phones anymore
* PSD2 for Fintech (Banks have to grant access to bank accounts for fintechs)
* Money Wires are very cheap or free within the EU. They can still take a day or two. Starting November Banks must offer "instant EU money wires". I think the time is less than a minute. Less than a bitcoin transaction takes to process.
* Military Headquarter in the EU, beginning of an EU army
Don't write the EU off. Nobody knows the future but for me the Brexit seems like madness.
