I was interested awhile back when we talked briefly about the effect that language barriers can have on the economy. I found this web site (http://www.us-english.org/inc/) whose purpose is to promote english as the official language of the United States. I think that english should be the official language of the U.S., and that every U.S. citizen should be required to learn english.
Language barriers can be an extreme problem in the workplace. My boss hired an employee over a month ago who could barely speak any english. After a few weeks of struggling with language barriers, the man was laid off. The result of the language barriers was decreased productivity in the workplace. That's only one example. Imagine what effect language barriers are having now on productivity all over the U.S.
There are some interesting statistics on the website previously mentioned. Of those statistics, I found it amazing how many millions of dollars is spent each year on translators, interpreters, and overall catering to the language needs of those who aren't willing to learn english. On the other hand, it could have a positive effect on the economy by creating more jobs (translators, etc.). Go to the website and check out the statistics and let me know what you think.
