Pope Francis has released a sharply worded take on capitalism and the world's treatment of its poor, criticizing "trickle-down" economic policies in no uncertain terms.

In the first lengthy writing of his papacy — also known as an "apostolic exhortation" — Francis says such economic theories naively rely on the goodness of those in charge and create a "tyranny" of the markets.

"In this context, some people continue to defend trickle-down theories which assume that economic growth, encouraged by a free market, will inevitably succeed in bringing about greater justice and inclusiveness in the world," the pope wrote. "This opinion, which has never been confirmed by the facts, expresses a crude and naïve trust in the goodness of those wielding economic power and in the sacralized workings of the prevailing economic system. Meanwhile, the excluded are still waiting."
