Learning a language can be important

Will trade unions reduce outsourcing? Here is an article that asks this question, but it is about Indian trade unions, not US trade unions. Also, speaking english turns out to be pretty valuable if you live in India

Sanyal’s thesis is interesting. But before we anticipate that change, it is
necessary to address an important differentiator that has already emerged in the
job market today. It is the earning difference between those who are conversant
with the English language and those who aren’t.

Salary differences between equally qualified (non-professional/technical) candidates can be as high as 400 to 500 per cent. In fact, the more fancied jobs in airlines, hotels, media, banks and financial services only to those who know English, the rest are forced into less fancied assignments.
