Price, value and practical utility are not really correlated.
A Rolex and a Timex will both tell you the time. An iPhone and a $129 Android will do mostly similar things. A Toyota Camry and a Porsche will both get you to work.
But practical utility and value aren't necessarily the most important thing.
Apple intuitively understood this, at a time when other computer companies didn't. Lots of people look at a Macbook and see an overpriced computer that costs a few hundred dollars more than a similarly equipped PC, albeit in a pretty case. But that's the point - lots of people want their computer to look good!
Apple products are relatively cheap to produce - and they make an enormous margin on their hardware. But it doesn't feel cheap. The boxes are substantial. The finishings are high quality. The user experience is taken care of. Other PC makers might have been much cheaper, but you notice that to do so, they've cut corners in places.
I don't think the lesson here is in what he said, but rather that he made his customers feel like idiots. Only a fool would believe that a ring for £1 has the level of quality and craftsmanship that you'd get with a £100 ring, but you don't want to feel like a dumbass for buying it. You don't go to McDonalds with expectations of buying a Michelin Star meal. You go there for something warm & tasty, that comes out quickly.
