Is it true or is it just stereotype that a lot of Swedish woman are gorgeous blue-eyed blondes?
Or brunettes. Poland has them too though. Just not quite as many.
To answer the OP though, since I have lived in the US and in Scandinavia, the quality of life is like a hundred times better here. That's coming from someone who lived on a Southern CA beach for a while. The weather is cold for 6 months and it's dark for about 3 months of the year. If weather and money were the only parameters for quality of life things would be different. They're not though. When you add in free education, healthcare, cheap daycare, maternity/paternity leave, lots of vacation, sick pay, lots of holidays, awesome mass transit, pension plans, job protection, green and clean cities, amazing nature, and still an average salary that's in the $55,000 range it's really easy for most people to argue that the Nordic countries have it awesome. Get into the private sector, make more money, and enjoy a lifestyle that most Americans cannot even grasp.
