Anything that doesn't imply infinite growth is taboo... Which is weird because it will for sure happen, the question is whether you plan it or suffer from it
Yes. I don't think a broadcaster would accept a billion dollars for a 30 second "ad" during the Super Bowl with a message that said "buying this junk will not make you happy".
Making products that are hard to repair and which don't last long are the huge culprits. Also, when it comes to clothing, it is all fast fashion. Wear a few times, then dump.
Also labor costs to repair in the developed world is another factor.
