I shouldn't think one would have to be an adherent of biological psychology to appreciate what Miller is saying. Social learning theory alone could account for incessant craving without resorting to a genetic argument. But one way or another, the incessant craving to consume is a dominant feature of human life. Buddhists would say it arises from ignorance about our true nature. Christians would say it's evidence of original sin.
Evolutionary psychologists say it's wired in because it conferred reproductive advantages.
All agree we've got it. Erik Fromm believed that consumerism was a way of escaping the anxiety that accompanies human freedom and responsiblity. Behavioral psychologists would say we've been conditioned to consume through the elaboration of complex learned behaviors built upon basic biological drives. Psychodynamic psychologists would see all sorts of psychological displacements, repressed impulses, sublimations and compensations at work. While this is a very rich area for future discussion, David's concern to identify the addiction dynamics of consumer culture has a lot of merit.
