The real issue (which causes all the above differences anyway) is cultural. What matters is not comparing things, but comparing people, their attitude, principles, and way of life.
For me, Europe is an socialist dystopia which punishes individualism, risk-taking, private businesses, and where people don't have a passion for much, no hobbies, and no aspirations.
For any particular thing that people do, for example what hobbies they might have, but this could be extended to almost anything, what car do they drive, etc, anything that can be analyzed statistically you will find that the distribution for people in the US is far wider than the distribution for people in the EU. Whatever it is that interests you and is outside the median, you will find that there are people in the US who share your interests, but you will likely won't find the same to be true in europe. The distribution of anything in europe is narrower.
Let me give you a silly example. On average, americans eat far worse cheese then europeans, but if cheese is your thing you will easily (!!) find better cheese in the US compared to the best cheese I can find here in Europe. But that's not all, if you explain this to an average american who isn't into cheese, they will understand that cheese is your thing, just like they have their own peculiar things they are into. But I will not be able to explain the same thing to an european, all I would get is "what's wrong with our cheese?" and "you are stupid because our cheese is great".
This is not a thought experiment. I have done this exact experiment with cheese with many americans and many europeans. As silly as the example is, it illustrates the point that europeans simply cannot accept that you might care about things they don't care about while americans understand this idea very well, even if they don't understand the thing.
Let's take another example, general aviation. It's an expensive and rare hobby even in the US, but even middle-class people can partake in it, and they do, it's a thing with communities associated with it. It's not a thing here in europe. It's extraordinarily rare, and it's extraordinarily expensive -- not relative to european incomes, but in absolute terms -- GA is fantastically more expensive in europe compared to the US, so you have to be made out of money, and if you do it at all, it's not a community thing.
Just search youtube for anything, any kind of activity that you are interested in, and you will find that the majority of videos are produced by americans. I posit this is not a coincidence.
Someone might claim that's because all these activities cost money, and it's not simply the fact that europeans are not interested in these things, but rather that they don't have enough money to do them. And therein lies the problem. The reason europeans don't have money is because doing business here is a terrible endeavour stiffed at every step of the way. People don't really start businesess, and starting a businesses is shed in a negative light societally. People see their bosses as their enemy (from which they require mandatory (!!) union participation to protect yourself from).
Mind you, not any particular boss they might have, which might be terrible as a person, but the whole concept of "us workers" vs. "they the rich people". Of course, your direct manager is very unlikely to be rich, but in most people's minds the bosses are "part of the oppresing class" and they are the enemy that the state must protect themselves from. The idea that you might even become a boss one day, say by starting a business is ideologically rejected. The regular people are the good people and they don't join the enemy by becoming the oppresor.
I could go on and on, but the gist of it is that I have trouble finding people here in europe who I share values with, but I have no such trouble in the US.
