And I don't mean that in a particularly bad way; most religions package a bunch of useful concepts (e.g., the golden rule) with some stuff that isn't literally true but does serve social and emotional needs in ways that the useful stuff gets passed down through the generations. As scholar Huston Smith put it, religion gives spirituality historical traction.
The notion that markets can drive efficiency is a valuable insight. But people for whom Econ 101 acts as a religion have a really hard time noticing when that effect gets swamped. This is pretty easy to spot these days because you'll find nominally pro-market people cheering oligopolies and monopolies, or getting upset at regulations that make markets more efficient. One easy test is how they feel about sustained high profits. To people who value markets for their ability to drive improvements through competition, that's a sign of something wrong, like insufficient price competition.
