It appears that "the good" is losing.
because they are not "FoB" (Friends of Bill),,, edit,,, some, like Jamaica and Puerto Rico, seem to thrive whilst Haiti with similar resources, are "S-holes."
"Why?" would seem to be an appropriate question.
I'd like to see similar maps just for the USA showing the more/less corrupt states. More/less corrupt counties. More/less corrupt cities.
But that said, this map is not really a surprise. Nations with freer market systems are less corrupt than nations with state controlled markets. The map certainly shows that pretty well.
Unfortunately it's time to add the USA to that list?
