Ok everyone, you are wrong. The arts are applied in multiple things. Without knowing any of the arts or graphic design, the world would not be what it is today. Art is necessary for advertising and creating websites. Sure, plain art like painting really doesn't benefit society, but others do:
Art is used for:
Graphic Design
Website Design
Advertising
Criminal Tracking (police drawing the criminal)
and many more.
What is sports used for? A lot too, but it doesn't contribute to society as much as art. Sports have much narrower jobs, as footballers can only play football, perhaps coach about football, and talk about football. Very narrow.
