With its age-old fascination for education, southern states have done better than the North.Start-ups, IT hubs, and industry majors setting up shop have changed the face of the South.Nearly 79% of global offices set up by international conglomerates in India are in the South.Almost 46% of tech unicorns are from the South.The GDP per person in the South is 4.2 times higher than the North.None of these indicators can be ignored by any central government, whatever the political compulsions, notes Ramesh Menon.
