This article brought back memories of my childhood. Most families had "only" one car, and it was not at all unusual to borrow a neighbor's auto in an emergency situation. Now, we have more autos than licensed drivers in the U.S., and I cannot remember the last time a household auto was driven by a non-family member.
The magazine article cited the obvious example of Zipcar, a car sharing service where a member pays only for the time they actually use a car. If you think about the money an auto costs you in insurance, depreciation, and loan interest versus the limited amount of time you spend driving, it is easy to imagine how cheap Zipcar can be if you don't need an auto to get to work.
Even beyond autos, the article cited emerging examples of sharing large-ticket items such as housing (renting out unused bedrooms or couches), and ride sharing. One can easily think of other examples: a street of homeowners chipping in to buy a rising lawnmower, communal vacation homes or RVs, or practically anything that requires a relatively large capital outlay but is used very little.
Now, the marketing question is what impact might this trend have on various sectors? If it were to become widespread, the need for manufactured goods might well decline as more families share a given purchase. But there might also be a need for better-made goods that are able to last under varied and increased use, and manufacturing those might require more labor and carry higher margins. And one can readily see potential for this in many service areas; in fact, it may already be here with such offerings as cloud computing and VirtualpcConnect.
In the long run, this trend may reduce employment in raw manufacturing and duplicative service entities. But this should be offset by an equally huge increased need for repair personnel, logistics experts, and the like. As with many possible trends, the question is not so much predicting what will happen as making sure you and your company are flexible enough to not get trampled in whatever changes come.
