Are you kidding me with those analogies?
So the only person that can a moral high ground is when they eat only the produce they planted, build their own phone device and also educated themselves without outside assistance.
So tell us, why have you been "watching" repladies for YEARS now?
I don't think you stand on the moral high ground for buying a $20K bag, no. The bag is pretty, the leather is really nice, and you may well enjoy having it a lot. Having it doesn't make you a better human being, though. You're exploiting other human beings for the products you use, just like everybody else. So maybe you feel good about paying French workers with social welfare benefits for your handbags, but you're still depending on Rohingya refugees working 60 hour weeks in meatpacking plants for your steaks. Welcome to capitalism, where you can't shop your way to virtue.
I think RepLadies is fascinating. I got there because I bought a bag in Italy in 2005 because it was super practical for what I needed. I carry a lot of stuff, and if the handles on my bag are attached by rings, they shred. I was on the street and saw a bag with handles sewn on firmly, so I bought it, not knowing it was a Birkin rep or what a Birkin was.
When somebody pointed it out to me, I got interested in the rep industry. I'm an academic, and a lot of my work is on supply chains (mostly in agriculture, but sometimes in factory-made goods). Repladies opens all sorts of interesting questions: How do the rep makers make money on these? Lower labor costs? Lesser quality materials? Low marketing costs?. Then I got interested in the sociology of reps---do people buy them to display status? Because they like the design of the bag for some reason? What's the actual difference between rep and auth that produces the value differential, and is it material or social? If you're interested in how markets work, reps are a fascinating case study. I don't quite get the frenetic QCing over at RepLadies, but their general attitude is a hoot.
I don't particularly have any interest in any kind of handbag, rep or auth, as a status symbol. There aren't a lot of people in a university who know or care about branded mass market luxury goods, so who would I impress? Birkin-style bags do make really good book bags, though--they are nice-looking and the handles hold up extremely well.
