In short, sustainability is a means to
justify policies pushed by some interest
group. This reflects a chronic problem in
amateur efforts to deal with economic
issues: Well-established economic concepts are overridden because they would
force society to consider whether the
results of the sustainability policies truly
are desirable. Instead, those concepts
are replaced with touchy-feely slogans.
The results always are serious and persistent
errors. Thus, the Chicago tendency
to push conventional economic
principles as far as possible has a marked
advantage over the proclivity of too
many others to stress the limitations of
economics. In short, seeing the doughnut,
not the hole, is preferable.
