The problem is that each of th eEU countries is a country. With its own interests, culture, history.

We are eons from a country such as the USA, which highlights how federal it is. It is still one country, with one president, one army etc.

We (in the EU) are countries that love or hate other for over 1000 years. Some of the dislike is deep, some is surprisingly different now (France and Germany for instance, forever enemies and now counties that are really close to each other thanks to the post-war efforts).

But when it comes to money and politics, we are often each for its own.

that's true, but in my opinion younger generations feel they are European more than anything else.

Even I, in my middle 40s, consider myself European before being Italian.

And I am proud to be from Europe, more than I am proud of my country (which I am not for so many things).

it's unlikely to be the norm, most people are most likely consider themselves to be a part of the group that they hear most about from their favorite source(like tv host or YouTuber)

do you think for most people its a "group of Europeans"
