The reason that Plato banned the artists from his republic is that he felt they would tug on emotional heart strings and sentiment would get in the way of truthful description.
The world is full of clever people who talk the talk but don't walk the walk
I encounter people coming up with solutions to problems before they have fully described or delved into the problem. For some hard to fathom reason they don't talk to people who might know more about the problem than they do. They are more concerned about looking good on paper to those above them in the hierarchy than an honest and open dialogue with those below them in the hierarchy. The lazy solution is accompanied by slogans. eg. "No child left behind" (reality check: we did leave quite a few behind)
Programmatic solutions often don't work even though they look good on paper. The nitty gritty reality on the ground, the tremendous suction generated by dysfunctional forces can tear the program to shreds. The makers of programs often hide in their offices and leave others to be the sacrificial lambs of their failed paper work.
As their failed solution spin out of control, they plan the next step in their career pathway.
I like the Iris Murdoch quote about the artists: "Rilke said of Cezanne that he did not paint 'I like it', he painted 'There it is.'"
In more detail the Iris Murdoch quote goes like this:
"One might start from the assertion that morality, goodness, is a form of realism. The idea of a really good man living in a private dream world seems unacceptable. Of course a good man may be infinitely eccentric, but he must know certain things about his surroundings, most obviously the existence of other people and their claims. The chief enemy of excellence in morality (and also in art) is personal fantasy: the tissue of self aggrandising and consoling wishes and dreams which prevents one from seeing what is there outside one. Rilke said of Cezanne that he did not paint 'I like it', he painted 'There it is.' This is not easy, and requires, in art and morals, a discipline. One might say here that art is an excellent analogy of morals, or indeed that it is in this respect a case of morals. We cease to be in order to attend to the existence of something else, a natural object, a person in need"
