A issue with today's programmers is that they require instant gratification from their programming languages. Remember that it takes a large investment to learn a foreign language. The more you learn, the more you can express. Haskell and FP takes times to master because they are powerful tools that allow you to express complex ideas succinctly. That's not a selling point unless the ROI on that time investment is good. It's a problem with the language and not programmers if there isn't a more gentle learning curve.
