Pay the Artist

This suggestion is one of the most intriguing among the group for me. I think this is because there is almost no substantiating evidence for Salmon’s claim that investment in the arts creates jobs.
Salmon says that the fact that artists spend money quickly and carefully which is why it is so beneficial. But is this true for all artists? And, again, where is the evidence that art employs more people than, say, a nation effort to construct new highways and other infrastructure programs?
I am very uncertain about this suggestion. I wish there was more to go on than a lofty accusation the arts are more profitable than infrastructure.
