That sounds plausible on paper, but as a matter of practical fact when I want to get a job done in a hurry and I try to do it in Haskell I get treated to the challenge of solving a series of puzzles in type theory, whereas when I try to do it in Python I just write code and it works, so while I agree Haskell is an interesting and elegant language, when what I care about is accomplishing a result rather than the mechanics of the language, I reach for Python.
