I'm not usually a big fan of Popery, and I am usually a fan of free markets, but I like this from Pope Francis:
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.
It's probably evidence of an inborn human need for religion that even atheists often seem to have a desperate need for something spiritual, even if it's only atheism itself. For many, free market worship fills that role. Like any religious fanatics, they won't be discouraged by having the fact of this sacralization pointed out - but the rest of us really should take note.
