Francis said trickle down policies have not been proven to work and they reflect a “naïve trust in the goodness of those wielding economic power.”

“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,” Pope Francis 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,” the 76-year-old pontiff added.
