Well, it is high time we realised the problems of a centralised economy India has been pursuing since Nehruvian times following the European model of economy. Heavy investments were made in Mumbai by Central Government thereby making it financial capital of India and alas we now are in this pathetic situation where non-Maharashtrians are unofficially declared outsiders in Mumbai.
It is time now to move to a decentralised model of economy whereby Central Government, to start with, develops all states equally into economically sound engines of growth by pumping in investments and facilitating FDI.
To start with, Each state capital city in India should be provided with uniform infrastructure of world standards, job providing capacity and development opportunities. This will be a great step in reducing regional imbalances in growth and can to a large extent bring down the migration of labour from all India to metros like Mumbai. Instead migration will be more from each state to its own state capital than to a handful of metros like Mumbai.
Till then I guess we will keep hearing this kind of "son of soil" utterances from more states that have enjoyed higher investment from Central Government all these years.
