"[E]conomics is the study of the allocation of scarce resources. But if resources aren't scarce then how can we study the allocation of something that doesn't exist? Of course, you might think that most economists are only discussing angels on pinheads anyway. And if we're honest about it all economists would insist that at least one current major theory is nothing more than that. But in the entire absence of scarce resources, economics would be even more like that. Akin to asking whether those angels could waltz or jitterbug upon their pinhead."
