I think Louis Vuitton themselves is partially responsible for some customers preferring the "MIF" label. Part of their marketing and branding was always focused on the trained artisans IN FRANCE who sewed their bags. So you could perhaps wrongly assume that you can't hire trained artisans lickety split in other countries, that perhaps these artisans are not instantly available or would take a long time to train.
Now it appears that is not the case at all. LV has opened factories in Spain and the US and additional ones in France, and the bags are probably the same quality. LV had to keep up with the high demand so they trained people quickly, it would appear.
In general, I love to buy products MADE IN THE USA, but there is a slight niggling sense in the back of my mind that the 75 year old guy who does the best job in the factory is probably located in France.
After hearing all the complaints about cracking, peeling, and the logo not matching up, I fear the 75 hear old artisan is getting a little cranky in old age. Lol. 😃😃
