I think we're getting away from the definition of Veblen goods in that it implies people wouldn't want a Tesla, Mustang, or iPhone as much if you cut the price in half. And that seems manifestly silly.

On the other hand, I can absolutely imagine that a lot of the people who buy supercars would be less likely to buy a Lambo, given it's downsides, if it were something any upper middle-class household could afford if they wanted to.
