This is ridiculous. I think you are seriously missing the point of PL research. Furthermore, I can not even imagine what your definition of "helpful" is when you say not ".../powerful/expressive/...". I honestly can't even argue with you if you do not think power or expressivity is beneficial.
PL is not a buzzword-oriented culture. No (serious?) language designer creates a language with the intent of making it harder for programmers to do their jobs. (Brainfuck and other Turing traps excluded.) That said, being "helpful" can be interpreted in many different ways. And of course, every PL designer does interpret it differently!
OOP took off because it was a revolutionary way of structuring your code so it could be easily used, reused, and maintained. The point was to help teams be more efficient!
Functional Programming is so worthwhile first off due to immutable types. This allows highly parallelizable code. You don't have to worry about race conditions because your objects are read-only! The emphasis on types also allows better ability to prove correctness of a program before run-time. Finally, all FP languages (that I can think of) are highly expressive. This means that you can write the same program in (OCaml, Haskell, CL, Clojure) in a shorter amount of time than you could in Java/C#/Obj-C.
If you still think there is "a lot of unnecessary stuff going on in CS", I'd really like to hear what you think is necessary and we'll go from there. I already discussed your "fewer bugs and shorter time-to-market" points.
