The pope fails to make any genuine distinction between Western poverty (bad enough) and the poverty of the Third World (unimaginably terrible). But is it really true that absolute autonomy of markets and financial speculation are the driving reasons for poverty and inequality? People in places such as Congo, Burundi and Mozambique live under corrupt authoritarian regimes where crippling poverty has a thousand fathers none of them named capitalism. The people of Togo do not suffer in destitution because of some derivative scheme on Wall Street or the fallout from a tech IPO.
Without the function of financial speculation, there would be a heckuva lot more poor people.
