The Pope also used the phrase “free market”.
Huh, you're right! On page 46 (from here) he said--
"...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. 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."
I'm not happy with Pope Trickletrickle...
** trickle-down theories**
Exactly what is mistranslated.
