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 norway 149
sweden 172 finland 130 denmark 16 that is over 467,000 square milesvs 25 million in ? square miles.
nyc is 400 square miles the surrounding counties are 4000 at mostgive me a minute for math.
so 467,000 square miles vs 4400 square miles
so NYC is 100x per square mile makes it very very hard to be fair and divide wealth correctly
