Well, that's true for pretty much any luxury brands. Look at how many people pay for the fancy "designer" clothing items and accessories with branding plastered all over it (Gucci, MK, Boss, etc), where the quality isn't any better than the "pleb" versions, and they're often more expensive than custom tailored items that'll look way better.

Vanity purchases are absolutely a thing. I'm glad my wife was cool with a relatively inexpensive ring (<$1k) and doesn't care much for jewelry in general. But the rest of her family is another story, and they love all of that vain nonsense. So instead of wasting all of our money looking rich, we're able to afford things like a home and plan for retirement.
