Not to mention that parts of Europe (and the EU) are actually less controlled in terms of actual enforcement of labor regulations, corruption and organized crime than I would probably say any parts of the US mainland, this includes parts of Italy and not to mention the Balkans. I also don't want to sound too negative, LVMH is running a legitimate business and it is what it is. But I still think it's good to be aware of realities and forget about 50 year old craftsmen in a Haussmanian lofts with cobblers tools. There are independent states within the EU with such large scale corruption and organized crime that have been characterized as mafia state and if you count the Western Balkans, places that are hot spots for human trafficking. Labor is cheap there and so you will find sub-contractors (and perhaps especially sub-sub +contrators) in these areas for LVMH and kering, even if they should have relatively good control with the conditions at the sub contractors they use and avoid big issues.But I find it curious how Americans view European things sometimes. Don't want to get too off-topic, but let's just say that Europeans aren't automatically cooth and not every handbag maker in France is a Hermes artisan with 20 years of experience. Business is business... Talented (and not talented!) people are everywhere, and where the material comes from often doesn't match where bags are put together anyway. And honestly in a handbag the actual material is arguably more important. Surprisingly separate part of the business, material supply.
Also a little context on salaries. The dollars is very strong right now. The minimum wage in France is about 1700 dollars a month and that is more than likely more or less what many workers at LVMH factories make, perhaps a little more depending on different circumstances. Given a 35 hour work week, that is about the same as 13 dollars an hour. In Spain, Portugal, Italy and not to mention Romania, wages in these jobs in general should be lower.
There are ateliers in Paris where bags are made, but these are mostly extremely small scale artisanal enterprises run by a few people. You can't run a huge luxury brand like that. Hermes does have a factory in Pantin which, for all intents and purposes, is in Paris (even if it's technically right outside of the city limits). In general, property prices are so high in Paris that there would have to be some very large economic advantage for the factory to be situated right there for it to make sense. It would be like opening a factory on Manhattan.
