What do you think about the lack of genre diversity in anime? Why do you think animation companies don't try to broaden the medium by making shows about medical dramas/mysteries or a political drama?
I'd assume it largely comes down to demographics and a need for safe returns. I don't think many production committees want to invest in a show targeted at a demographic that doesn't exist yet and doesn't necessarily exist at all. Especially when anime already has an ingrained economic model that assumes people will buy extraordinarily expensive products as collector items, something many people outside of anime's existing market would likely be much less willing to do. Then there's the fact that anime often is intended as an advertisement for other stuff, which would be less effective when the anime itself isn't something that would appeal to anime's existing audience.
There's likely a host of other reasons as well - I can only make guesses based on what I know of the model.
