First of all this policy shift will profit all the wealthy of the entire world: the rich of the developed countries and in the Third World. "Billionaires of the world, unite!"
The wealthy of the entire world have special interests leading to tensions which exist among them. But above all, they have common interests to defend themselves, and that is why they organize in a sort of new nomenklatura to present a common front before the "danger" (in their eyes) presented by the poor everywhere.
Hence, as a conclusion to a tragic confusion, instead of attacking poverty -something that would require sacrifice on their part -- they attack the poor.
