To give you a rough idea: Hong Kong topped the list. The USA is tied for sixth, Canada is tied for eighteenth, and Cuba and North Korea are at the bottom of the list.
These rankings were broadly divided into four categories: "free," "mostly free", "mostly unfree" and "repressed."
Now, these are the tidbits I found interesting:
"'Free' countries in 2000 had an average per capita income of $26,855, while 'mostly free' countries had slightly less than half that."
"'Mostly unfree' economies averaged only $3,229 in per capita income".
Wish I could find the median incomes, and not just the mean.
