They loot their countries, swim in a sea of wealth and stash funds away from their empoverished homelands, mostly in Western foreign lands, while their people are starving or dying from easily preventable diseases, and their killing squads are brutally murdering those who dare to speak up against corruption, embezzlement and tyranny.
"They" are tyrants and corrupt foreign leaders and their relatives and confidents. They come from all over the World. Africa counts many. After siphoning the economies of their countries, they use the loot to buy mansions, private jets, yachts, rare paintings and artworks, luxury apartments, jewelry, million dollar cars, and other expensive items in the West or hide the money through shell companies.
