There is a lot to be said for the common critique of economists: They see society as the product of freely acting, rationally calculating individuals for whom monetary reward is the primary source of motivation. Free markets, to them, are the pure expression of social function and economic growth through their realization is the only outcome that matters.
But people do not simply act rationally to maximize their economic rewards, because they can have incomplete or inaccurate information, ideological biases, conflicting desires or collective interests. Exploitation, dishonesty, violence, ignorance and demagoguery set vast areas of social life apart outside the model. The multiplying exceptions overwhelm the rule bringing the model’s utility into question.
