you hear all the time "the EU cost us soooo much, what does the EU do for us?"
People are so ignorant, cause they don't remember, how it was once. I am out of a generation that had the experience!
One phone number for emergency calls, you can visit a doctor in another EU country with your insurance card, no passport needed into EU, no problem with your EU driver license, you pay the same price in a foreign EU mobile phone net, like at home etc.
Just more of EU standardization! 👍
