You have to remember, I didn't raise the example of the US here. You did that unfortunately and I was only trying to counter that.
States are not divided solely on language in India, some of them speak in the same tongue (UP/MP etc). We just split some of the northern states if you remember (Jarkhand/Uttaranchal), all of them speaking the same language. States were created to permit ease of governance. We just put in our logic, language, colour and religion to help us divide ourselves more and this is the sorry state of our nation.
In your post you started off saying education but the same argument extends to labour intensive jobs: there is something called hard-work, people generally employ whoever works harder, better and faster and they should also. Throw the quotas/reservations out and just because you are a marathi does not mean you should get paid IF you slack irrespective of where he was born!!!
