Your argument is on point but it lacks the two that will drive the century to come: - clothes are cheap because they are mined/manufactured/transported mostly with energy coming from fossil sources, and the IAE itself says that Oil has reached its peak. If energy goes down, production can only go down (yes, processes have been more efficient, but the efficiency has only transformed into even more stuff produced. That's the Jevons effect) - clothes are cheap because their pollution, chief among them CO2 emission, is "free". But it's the kind of cost we'd rather not be paying
