Not sure I can agree. You would replace your air conditioner once options with way less power usage or more comfort are available, but your still good machine will make someone else happy. I still replace some older lamps with LEDs when they die. TVs just go on a rotation, replace your bedroom TV, make your grandmum happy, it is going to make someone else happy. People still look for quality CD players (especially AMP combis) in second hand shops around here. Someone must be buying new devices so the second hand market can work. Without well working second hand market you need cheap china devices so people get access to technology. It's no problem for this approach if YOU want to buy new things. Another example might be cars. Someone must have the need/enjoyment to drive a fully new car so I can buy that same car a year later at a much more reasonable price.
