What does prosperity mean? One Institute tried to measure what it is. These lists have their strengths and weaknesses. It all depends on the assumptions you make and what you consider to be the important outputs. But, they're still interesting.
It's good to be living in Nordic countries, or countries that speak (and have the cultural leftovers of) English. But, that gets backed the arguments that I've heard before, that if you have small homogeneous (culturally and genetically) populations you can have a Welfare state AND wealth. Else, you need more (relatively speaking) capitalism, to get prosperity.
