From the little research I made I found out that NORWAY, SWEDEN, DENMARK,and FINLAND well honestly speaking these countries prioritize social welfare and provide a high standard of living for thier citizens, funded by thier tax system.
Norway - 2 million population
Sweden - 10 million
Finland - 5 million
Denmark - 6 million
We won't know the true scale of standard of living for these nations.
Until their population sizes grow comparable to the USA or EU.
Achieving high standards of living is much easier for small, sparsely populated nations.
Than it is for larger countries.
empty areas have an advantage.
New York City and its suburbs are about 25 million people
those four countries are 23 million people.
So 23 million in ? square miles
vs 25 million in ? square miles.
give me a minute for math.
