Mike the Mad Biologist [ht: sm] casts doubt on the idea of scarcity. And for good reason:
While they seem to have receded somewhat, a couple of years ago, there were quite a few arguments about the fundamentals of economics (especially macroeconomics) and how to teach them. As an outsider, one thing that struck me as odd was the emphasis on scarcity (e.g., economics is called the science of scarcity). It’s odd because, at least in wealthy societies, there are very few scarce items. We’re definitely not slacking in our ability to produce calories, which arguably for most of human, if not hominin, history was the vital concern.
Mainstream economists, as I teach my students, start with the idea of scarcity—the combination of limited means and unlimited desires. And then, after a great deal of math and a wealth of assumptions, they prove that a system of private property and free markets provides a perfect balance between those limited means and unlimited desires.
But, as I also teach them, the mainstream presumption is that scarcity is universal—both transcultural and transhistorical. In other words, they start with the idea that all human beings, in all times and places, have had to confront and solve the problem of scarcity.
An alternative is to see scarcity as an institutional, historical and social, phenomenon. In particular places, at particular times, the existing set of economic and social institutions makes certain goods and services scarce. Thus, for example, oil is scarce because of the particular configuration of the energy industry, the personal car and truck culture, the government-sponsored expansion of the highway system, and so on. That’s what makes oil scarce. Similar stories can be told about the scarcity of water, arable land, good public transportation, high-quality mass education, and so on. Their scarcity is the product of particular sets of institutions in particular societies.
Why is that important? Because, as against the assumption of mainstream economists that scarcity is always with us (and therefore can’t be changed), the idea that scarcity is an institutional phenomenon means that changing economic and social institutions can change or eliminate scarcities.
The same applies, of course, to abundances. Right now, we’re living in a society that has created a surplus of labor (and, as a result, stagnant wages), which is part and parcel of capitalism’s law of population. If we get rid of capitalist institutions, then we can create a new law of population, one in which the labor workers perform and the value they create are not turned against them.
