> The EU was supposed to bring countries together, but I think it did quite the contrary

What are some concrete examples of how Europeans countries are now further away from each other, since the start of EU and because of EU?

As someone who enjoyed the ability of freely moving across the continent to find a country I'm actually comfortable living in, it's hard for me to imagine EU made countries more distant to each other, but I'm not all-seeing and would love to understand more from another perspective.
