Hindi is taught is schools...its you who dint gave it importance its not about what benefits you get from speaking Hindi..its more about what most states prefer to interact in.

Out of 39 states 20 prefer interacting in Hindi..even when they all have different mother tongue. Its just the minority south states prefer speaking in there languages which doesn't matter to other as no migrates there( non existent)

I speak Hindi, and I have studied in the south. I think the best argument to lance this boil is this

“Let’s speak Tamil or kannad. These states are doing supremely better than all of the Hindi speaking states. Obviously language has something to do with our success, and it would be wrong of us to keep it to ourselves when it should be used to help the nation.”

This short circuits enough wires, and is polite enough to not engage the depressing flame war that is sweeping such discussion.

It’s not logical, but most of this argument is not logical, the proof of which is too much for the margins of this comment.

Not saying you are wrong but it doesn't make sense to me. Hindi is not the native language of any of the states anywhere in India. They all have multiple native languages. The whole language issue is because of the unfortunate language politics in South India but the same flames could be fanned in any part of India believe me. For example in my state (Rajasthan) I am pretty sure there are at least 4 dialects. What's amazing is that nobody is offended if we keep using a foreign language to do all the mediation but as soon as the majority understood Indian language is mentioned everybody is up in arms. I am forgetting the name but a recently passed away Tamil celebrity had made a famous satire on this situation, where everybody must speak in Persian.
