What we in Spain consider "making it" is to enjoy life, having time to relax, pursuing hobbies, spending time with family. And not having to worry about healthcare bills and pensions. We don't need a lot of money for that. I don't always want more. I just want enough.
In the US the vast majority never "makes it" and they are far worse off than we are here. I think Europe is great the way it is. I would not move to the US even if I was offered a job there. In fact I don't even want to visit and never have though I've lived in many countries around the world.
