Role of arts in economic and technology?

Generally art encompasses things without concrete answers, such as one piece of art being more beautiful than another. Economics and technology generally deal with things that are concrete and measurable, such as how fast can a PC run. Art is subjective and the others are objective.

With that said, all three elements support themselves in the US. Art and fashion are blended into the cost of it, for example. Technology is used to mass produce clothing.
