Why would you not want to learn other languages? I speak Russian, German, Chinese and Dutch, and can get by in Spanish, French, Bulgarian and Serbo-Croat.

Whenever I've traveled, it's been a pleasure to be able to communicate with people I wouldn't otherwise have been able to connect with.

Learning other languages also gives you a window into other cultures and ways of thinking. It opens access to additional literature, music and (as noted, and most importantly) people.

Personally, I can't possibly understand what the legitimate objection to a second language requirement in our schools could be. I can see plenty of good arguments in its favor.
