By what measure? Haskell can be a huge productivity multiplier. The standard library is built upon many powerful, unifying and consistent mathematical abstractions. For example, there is almost no boilerplate to write for any traversal, mapping, error handling etc. The average Pythonista simply has no idea what they are missing. But Haskell doesn't have anywhere near the third party ecosystem of Python, so is less productive by some measures.
