On the world stage, it is not about how much money each individual makes. The currency issue is does not translate into wealth. You can only measure an economy by the standard of living. In Zimbabawe, factory workers are making millions of dollars (whatever their currency is) a week. Of course a house costs hundreds of millions. In fact, I think bread now costs almost a million $. There are not very many wealthy folks (by the standard of living) left in that country.
I know that... it's not the average the people earn it's the median.
And the healthcare and the schools available for reasonable money and and and... in the moment I guess scandinavia is the place to live.
