The National Enquirer published an article called "Unspeakable Tax Waste" (August 6, 1985) that complained that the Department of Education was wasting U. S. tax dollars providing colleges and universities with funding to teach students "obscure foreign languages" such as "Dinka, which is spoken in the Sudan" and "Telugu, a language of southern India."
To me, this attitude is shortsighted as well as downright ignorant. It might even be called racist.
Language is the gateway to understanding and appreciating other cultures. And since the United States has diplomatic as well as other ties to countries around the world, it makes sense to train people to speak a variety of languages, no matter how obscure. Certainly the people who speak these "obscure languages" don't think of them as unimportant.
The newspaper amNew York (now called amMetro New York) cited in a November 24, 2014 article the work of Ellen Bialystok, a neuroscientist, on the benefits of bilingual education. She "found that people who are bilingual tend to maintain better cognitive functioning with age and, " continued the newspaper, "are even believed to have delayed onset in Alzheimer's symptoms after diagnosis."
Also the "obscure languages" that the National Enquirer writer disparaged could very well be the source of new words, useful words in English, a language that has adopted many words from other languages.
