Have you found any commodity where there isn't a push to lower the cost? That's pretty much what capitalism does.

Staff ex:Nurses are generally treated as a commodity in many economic models.
Music/Books/Movies can also be treated like this. Sure, as a consumer I might pick A over B, but movie theaters don't individually price movies based on quality.
For example, 'a cow' is not a commodity... but a grade 3 live steer is.
Movie theatres do not price films based upon quality, but the distributors certainly do (I managed a movie theatre). You cannot commoditise a movie ticket, each theatre provides different facility and presentation quality.
However, animals are also sold in bulk without individual prices.
