How Consumers Shop Differently Today by Sean Gregory, Underhill describes how American consumers now fall into one of three groups: Those who have lost their jobs or are about to lose their jobs. Those who are not in danger of losing their jobs but know someone who is, and as a result, have curtailed their own spending. And, those who have a lot of money but have learned that "conspicuous consumption is bad" and now see spending--or not spending--in moral terms. "The era of bling is over," he says.
Throughout the interview, Underhill shares his thoughts on where retail is and where it's headed. He talks about how the quantum growth of access to information (Internet, phone, etc.) has changed shopping. He believes that "we have reached the apogee of the big box. Growing the store any bigger does not translate into the customer spending any more time or money." He also thinks that "as a culture, we are over-stored. All store chains would be healthier if they were smaller."
While Underhill is speaking specifically about the American consumer and retail landscape, a lot of what he says is pertinent to Canadian retailing. It's definitely worth checking out.
