france isn't on the list either... shame
This is a useless list, because the parameters aren't included, if they rate useless items, then the list is useless.
Income is an important issue, but so is taxes...
Healthcare is important, but so is availability...
weather is important, but so is housing availability...
In any way you measure, I figure the US is at the top of the list (if you want to work for it).
If you want to not work, get free housing, free healthcare, free government cheese, and watch the snow pile up then the nordic nations would be appealing.
If you like trees and wild and woolly (and crazy) beavers, the french canada is the way to go.
If you want great beer, and a low crime rate (because the cops will shoot you in the street or beat you with spring loaded clubs) then Germany is the place.
If you want to look down your nose at the rest of the world, secure in your belief that; Your county is the best, all other countries suck, denigrate all foreigners, and have the 80% economy rely on those foreigners, Then France is the way to go
I'm sure there are others... But you can get ALL of the above in different parts of the US. Why go anywhere else?
