Video-Suggestion: "Is the European Union worth it or should we end it?" from Kurzgesagt.
I am clearly on the site of "it is worth it".
It gave us more then 70 years of peace and forms one of the biggest economic, scientific and union. We have a huge cultural and social variety that makes the union sometimes bureaucratic and complicated but also unique and liveable.
No generation before us could experience such a enormous wealth, education and safe world as we can.
