And that's amazing, and as an European I would never want to get rid of that. It's a cornerstone of our societies, a core belief if you want to call it that.
But I do think that there is a pervasive feeling of people being "ostracized" for wanting to do better than their neighbours. Like when someone says they are going to run a company the reaction is usually "why, isn't a normal job good enough for you?". Obviously this isn't universal, EU is far too big and diverse for this to be true everywhere. But I've met with this kind of attitude a lot personally, where people have directly asked me if I think I'm better than them by trying to do something good for myself and grow. So now I just don't tell people, or just say I work in software or something, there's no point. It's not even that tide lifts all boats, it's that "we're all in the same boat"(and don't you dare leave it) is a thing that exists.
But to be fair, I haven't really experienced that so much in other larger countries like Spain, France or Italy, at least not to that extent. Still I'd say it's different than the typical American Individual Exceptionalism, but probably a good difference, we don't to make the same mistake.
Probably a balance between the two is the right approach, you don't want to completely lack either sides, but also not be too dogmatic about it. But it's also hard for politicians to get votes on "You know, both sides have good points, lets figure out a balance", strong emotions sell votes and so on...
