Evangelical culture warriors have enjoyed a some-time alliance with the Roman Catholic heirarchy on some social issues, but not economic ones. Most recent popes have been socialists, or, at the least, very supportive of the rights of labor. In his first lengthy missive as Pope, Francis takes a similar line:
"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. 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."
He's absolutely right that "trickle down" has never been "confirmed by facts." Just the opposite is true. When the wealthy suck up the wealth, they are very careful not to let any "trickle down." Plutocrats are not philanthropists.
His critique of unrestrained capitalism, which may be read here, is similar to the one offered by my late friend, Fr. Francisco Fahlman, who was a priest in Moquegua, Peru for 40 years.
Fr. Fahlman was no friend of what he called "liberal economics." (It isn't what you think. "Liberal economics" is what they call free market-ism in Latin America.)
In the 1990's, Peruvian President Fujimori was pushing it, and Fr. Fahlman voted for Fujimori when he first ran. He did not vote for Fujimori when he ran for re-election because, as Fr. Fahlman acidly said it, "Liberal economics 'helps' poor people by getting rid of poor people."
