That has got to be a troll post. Nonetheless, on the danger of starting a flame war, here is a brief answer:

No, Haskell is not the obvious language. Though no doubt a very nice language, it is nowhere near the top of the most commonly used languages. Thus, it's money-making potential (in terms of available jobs) is pretty low - which seems to be the main factor the OP is interested in.

As for functional programming: much as I love it, it is not the non-plus-ultra answer to life, the universe and everything. And even if it were, there are other languages that are also functional; all the various Lisp dialects to start with.

And by the way, please refrain from personal attacks on HN.
