And if there are no candidates you wish to vote for, then why should you vote for someone you don't want?
That is why there is a need for None of The Above to be introduced as an option.
. . . plus by learning the language . . . you also learn the culture. And be able to understand it better. That makes real business sense.
While this might be true for other countries, it is not necessarily so for India.
English is recognized as the secondary official language of the country (with Hindi being the official one). Even lowly clerks in government offices speak English (albeit with an accent). The huge amount of information & literature available in English and the high percentage of English-speaking population in India make learning Hindi optional.
Moreover, even though Hindi is the dominant language, it is only one of many. If you are doing business with a company based in Bangalore, chances are very high that the mother tongue of your business partner is Kannada (which has almost nothing in common with Hindi).
Save yourself some precious time - learn the culture, skip the language.
How come everyone's going so slow if it's called rush hour?
