You could argue until the cows come home about whether there is such a thing as a new consumer or not. What Lewis describes is someone who is very busy and will buy some posh stuff and some cheap stuff according to taste and need. The old consumer was (and still is) someone who has time to choose and tends to stick to the top or the bottom end. A new consumer will have Prada sunglasses and a Primark coat, A B&O turntable on an IKEA shelf (but maybe he sent someone else to IKEA to get it because he's too busy leading trends to fetch it himself).
I enjoyed reading about the influences on and analysis of consumption but where the book disappointed me (and the reason I only gave it four stars) was that the end - the bit about how to flog stuff to new consumers - seemed unlike the rest of the book. It lacked the excitement of discovery that made the majority of the book such a great read.
Perhaps it was just that I like reading about people who sound a bit like me, but don't like to read about how to manipulate me into buying stuff, despite the fact that I work in retail most of the time. The end of the book appeared to have been added later to make it sell better to the ad agencies and marketing departments looking for the new new thing and a quick fix.
The bits written by Dr. David Lewis, chartered psychologist, engaged me more than the bits written by David Lewis, member of the Institute of Direct Marketing.
Still, a good read and a bit of an eye-opener.
