More than enough
If . . . we come to the conclusion, not to interfere in any respect, but to leave every man to his own free choice, and responsible only to God for the evil he does . . . this is all I contend for.
—Thomas Robert Malthus
I am constantly
surprised that defenders of liberty and free markets love to bash Thomas Robert
Malthus.
Maybe I shouldn’t
be, but consider this: Robert Malthus (his friends called him “Bob”) was one of
the primary interpreters of Adam Smith for the generation after Smith. Indeed,
a lot of people who pick on “Thomas” Malthus get Bob Malthus wrong.
That’s not to say
that Malthus was right about everything. But even more than Smith's, Malthus’s
economics built upon the idea that all humans similarly respond to incentives,
and he thereby rejected the idea of natural hierarchy. Writing in a country
that had excessive restrictions on labor markets—take a look at the poor
laws—Malthus was an advocate of free labor markets. And
Malthus argued that private property rights, free markets, and an institution
that would ensure that both parents were financially responsible for the
children they bore (that is, marriage) were essential features of an advanced civilization.
“Wait a minute,”
you may be thinking. “Are we talking about the Malthus who claimed back in 1798
in his book An Essay on the Principle of Population that
population growth would decrease per capita well-being? Isn’t this the guy who
argued that the combination of population growth and natural resource scarcity
would create catastrophic consequences, including disease, starvation, and war,
for much of the human race? And didn’t he miss the benefits of entrepreneurship
and innovation, blinded as he was by the fallacy of land scarcity?”
That Malthus—let’s
call this one “Tom”—is more a creature of the ideological opponents of markets
than of Malthus’s own writings. So maybe we should revisit Malthus and see what
he actually said.
It all begins with
a thought experiment: What would happen to human population in the absence of
any institutions?
The answer is the
population principle, which is the only thing most people know about Malthus.
And it’s largely correct. In the absence of institutions, humans are reduced to
their biological basics. Like animals, humans share the necessity to eat and
the passions that lead to procreation. To eat, humans must produce food. To
procreate, humans must have sex. If there are no institutions, human population
will behave like any animal population and increase to the limit of its
ecology’s carrying capacity.
The biological
model is simplistic; it treats humans as mere biological agents. It is this
biological model that produces all the results people usually associate with
Malthus’s name. And it’s not very far off from people’s conditions when their
institutions have suddenly been disrupted by things like conquest, revolution,
or war. (Consider the dual problems of war and drought that resulted in famine
for Ethiopians in 1983–85, for example.)
