Environmentalists rightly argue that we should be much more aware of scarcity. Resources run out; there is only so much waste that the earth can absorb; and exploiting habitats causes species to vanish. Environmentalists are not the only ones who recommend paying attention to scarcity. A budget, for example, is a representation of limited resources. Any household, organization, or nation should live within its budget. Raising awareness of scarcity is a project that I can sign up for.
On the other hand, some resources are not finite. We can make as many new cultural products as we want. Works of art, music, or literature from one cultural background need not deprive other traditions of space or resources. Ideas spread without losing their value; often they gain importance because of their diffusion. As Jefferson wrote, “He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.”
The Internet is another great example of a basically infinite resource. (Computers use electricity, but the amount of energy per byte is cut in half every 18 months.) More generally, there is no obvious limit to the growth and diffusion of human opportunity, so long as that growth takes the right forms. We cannot all get richer if that means that we all buy Hummers. But we can all get richer.
When scarcity dominates people’s thinking, they are unlikely to trust others. We may cooperate if we feel that we must, since resources are limited; but we seem to cooperate better when we are optimistic and expect everyone to win. There is “an association between distrust and economic insecurity and a limited-good view of the world” (Orlando Patterson, “Liberty Against the Democratic State,” in Mark E. Warren, Democracy and Trust, p. 155). Harry Boyte once argued on this blog that creative civic populism arises in times of optimism and growth, whereas narrowly technocratic and hierarchical politics is more typical when people are conscious of scarcity. Twentieth-century fascism played off scarcity, while FDR promised an infinite expansion of opportunity.
I would conclude that an awareness of scarcity is not intrinsically virtuous. It all depends on whether the good in question is actually scarce. We should be frugal with limited resources, but generous and extravagant with goods that that can be created infinitely.
