that the beauty of it, being marketable does not mean they have to design to a particular persons whims..
An artist who is good, but follows their own internal vision will usually create great works, and that will be **more** marketable than a design intended to target a particular person.
So even here it is in support of what Im saying, creating good art, by whatever mechanisms createt he best art, is inherently marketable because we value that as a people.
In other words you have the cause and effect wrong, an artist is marketable because we put value in good art... he doesnt create good art and is marketable because he is designing for the market.
