Maharastra has lot of laws to keep other states out even the northern ones
Thats why I will never teach my kids that India is country but an EU like system with lots of pride and prejudices toward each other.
I too believe south wasn't treated right, no matter how much hindi belt says about anti-hindi movements in south, I have seen a fair share of southies who are well versed in hindi but rarely the northern Indian knowing any popular southern languages.
Even CBSE use to have third language system and that third language was German what an irony, their first preference should be southern India's popular languages for third language system in Hindi belt and for south Hindi/other north eastern language.
