When it comes to learning another language as a marketable skill your mileage will vary massively. If you do not have other reasons for learning the language, your ROI could be negligible (or negative). To learn a language well enough for it to be of the level required ('marketable skill' level) will take a very long time. Even then, it may be unnecessary. I concur that communication is one of the most useful skills. My writing and public speaking always brings questions and is often a topic of conversation. That I (attempt to) speak the language of the country I live in and have knowledge of a number of others? It's never mentioned.
