Short answer: Because of the features you mentioned, You will be able to write code which is correct, self documenting, and achievable in fewer lines of code[.]. Your life won't be easier if you solve problems, because solving problems is hard. But you get a lot of benefits from using any language which has features similar to Haskell because of the above reasons. If you are into programming language research, compilers, theorem provers etc, Haskell comes with a lot of idioms, features and tools that it is a viable language for the tasks at hand. [.] a lot of languages rightly claim it like lisps and modern lisp derivatives, but Haskell brings with it a top of the line type system, (imo) a clearer syntax and tooling than OCaml, and a decent support from the industry and the academia..
