If we diverted billions of dollars to doctors or cooks we would gain the benefit of increased, more healthy lifespans.

If we did the same for bankers we would get, well what we got in 2008.

The difference between service jobs which are purely symbolic, in that they only work within human created environments, only interface with other people and ultimately the only arbitrator of how good a job they do are people and those which have to deal with the real world at least tangentially is huge. Artists and banker are in the former category, doctors, gardeners, cooks are in the latter.
