Absolute BS idea. Quotas should only be for people slightly less capable otherwise - like if someone is crippled in an accident. Quotas for any other person means that he is incapable.
Does this mean that maharashtrians are incapable?
Of course, a different question is: Who is a maharashtrian? Someone who has capably contributed to the state - like gujjus or southies - or someone who simply speaks 'the' language and does nothing else?
