Not sure I agree with putting doctors and cooks on that list. Providing services basic to life is not the same as supporting recreation, wealth, or luxury.
To put a finer point on it, doctors and cooks, along with farmers, builders, teachers, daycare workers, et al. existed ever since everyone started specializing. They directly support life needs.
There have been gardeners for at least as long as there has been civilization. Entertainers have probably always been around. Your idea of "life needs" doesn't seem to coincide with history's.
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.
