I definitely agree with the rings, but you don't buy many in a lifetime. Less so with the cars, the vast majority of cars sold are with relatively thin margins

I definitely agree with the rings, but you don't buy many in a lifetime. Less so with the cars, the vast majority of cars sold are with relatively thin margins. And houses aren't sold by a single business, it's just the law of supply and demand. I would add Nespresso as an example: They've definitely managed to mass-market a luxury good (outrageously expensive coffee pods)
