Having grown up in NZ at the same time as the Conchordes, I agree that having the latest, greatest stuff (toys, eating out etc) was not as important as going to the beach or playing sport with your friends. Pre-globalization isolation meant a lot of the latest stuff just wasn't available, so no one really thought or talked about it. Cheap global shipping and the internet means this is not really the same anymore.
Still, large North American cities are probably the easiest places to get caught up doing what other people think you should be doing.
