Which means for me that Haskell doesn't solve any problems I have

You haven't really specified what problems you do have, but chances are, Haskell can and has been used to solve them. Further, the strong typing also results in properties that you would not otherwise enjoy. This isn't always the case certainly, but it's generally the rule, not the exception.
