Are you even looking at the map you linked to? Do you not see the Asian countries (ex-Japan) colored in reds and dark oranges, while North America, Australia/New Zealand, and western Europe are in shades of yellow? The major Western economies have scores of 70+ (U.S., U.K., Germany, France, Australia), while the major Asian economies, ex-Japan, have scores in the 20's and 30's. South Korea straddles the two, with a score in the 50's.
