Discuss the following:
Producing any building or modern day movie is a very expensive proposition. Consider the truth that spending more for something does not directly imply that the outcome will be "better" or there is any real value in the fact that someone paid that amount. There are many bad movies, according to the critics, that cost a fortune to make and publishers regularly pay huge advances for books that don't sell. The same is true of all of the arts.
Use this discussion to explore what makes art valuable. During the discussion, you must develop your own prioritized taxonomy of various quality attributes that you believe make art valuable. Just because someone invests years mastering a technique or a specific genre does not mean the use of it will be valuable. It also seems that value should be much more than just scarcity. What are the elements of enduring value? (E.g. At one point tulips, during "tulip mania" were so prized that a single bulb could sell for as much as ten times the annual salary of a skilled craftsman. Needless to say, that trend did not continue for long.) Draw examples from paintings, sculptures, literature and cinema.
