there are a lot of companies who will hire programmers who competent at functional languages. Despite the fact that everyone and their dog is learning functional programming, only a very elite minority can utilize functional languages for common programming tasks. Companies are going to continue to use conventional programming languages because they know those are the only languages people can use. The only programmers who get jobs with functional languages are graduate level programmers who have a body of work with which they can demonstrate to an employer what they can do.
