Well, regarding South America there is a generation that grew up reading "Open Veins of Latin America: Five Centuries of the Pillage of a Continent" (even the author Eduardo Galeano has criticized his own work).
Blaming all the region problems on the "imperialists" and stuff like that is a line of thought still very alive and kicking around here - it is way easier to blame some imaginary entity than taking responsibility for your present situation. It is very inline with the current "outrage porn" culture.
