This gets into a weird ethnocentrist territory that disturbs me. Do we or should we care if a Lithuanian-born person, now a French citizen, sits behind the bench at an Hermes workshop in France? Or if an African-born leatherworker is in the Chanel workshop? Why is Chinese nationality an issue within the production of a Europe-located luxury business?
The point of complaint about China as a locus of production is, theoretically, not about the employment of Chinese people per se but about conditions and labor to cost ratios. Making an issue about the nationality of the workers in European luxury production can be a slippery slope toward "purity" concepts of the bad old days, and certainly not reflective of today's societies.
Late reply, but the issue here is not that the workers are, originally, from other countries.
The issue is that they are made to work in sweatshop conditions, for very low pay.
So, they are "imported" from China, to Italy, but are then treated and paid as badly as they would have been, had they stayed in China.
I wrote a kind of precis of a documentary about Prada using sweatshops like this, on this forum, years ago.
