The social policy advantages in Nordic nations and Western Europe today vastly outweigh those in the US. Growing up in the US, I was lucky my parents had good jobs and pushed me to learn and grow. If I did not have their support (and healthcare) I would not have survived college or medical issues at that time, some of which are ongoing today. I'm extremely lucky to have an advanced education, be healthy, and be less than 10k in debt 5 years after graduating. That's entirely due to my parents funding my education and medical bills best they could through that period as well as the insanely good benefits from my current position.
If I was born into a Nordic nation I think I'd have been better off. I'd have had the same supportive parents but no burden from education and medical debts, or stress of finding a position with good benefits before turning 26. I might even be freelancing or building my own company right now without fear of paying for prescriptions out of pocket for me and my SO which would be significantly more costly than our rent.
The US is a great country for opportunity but it is not a place of equal opportunity.
