An American professional will easily afford a car (and two cars for a 2-adult household), will be able to go out to lunch regularly and go out to dinner when they please. If they want to see a specialist for a medical issue they'll have an appointment in a day.
A Danish professional may not have a car at all for a few years out of college and will likely struggle to have a second car for their partner even as a senior-level employee. They will bring their lunch every day and rarely if ever go out for dinner. Their medical issues will take weeks or months to be seen if deemed non-emergency and they'll have less choice in which doctor they see.
It's probably easier to be at the bottom of society in western Europe than in the US, but for anyone in the American middle class their quality of life would go down substantially if the moved to Scandinavia.
