The World's Most Competitive Countries - Forbes.com: "At the bottom of the ranking of 125 industrialized and emerging countries, in worst to only slightly less bad order, are Angola, Burundi, Chad, Timor-Leste, Mozambique, Ethiopia and Zimbabwe--a gazetteer of economic blight."
There you will find photos related to the least competitive countries. You might use that as a guide to pray for the poor.
