You're quite right, we probably don't. I don't live in Australia so I have no idea what the cost of living is over there, or what average wages are like. However, that doesn't affect my point of 'if you can't afford it don't buy it'. That applies to everyone in the world. No doubt if/when I start a family I won't be able to afford much new stuff and so won't buy it. I'm sure there are plenty of people around the world who can't justify spending £20 on a box of plastic, so they don't, why are people in Australia, Borneo or Timbuktu a speical case?
