Ah come on.. where was south India in the 60s, 70s and 80s? All of the country's productivity was from the North Indian states.. So at different times, different states push the nation and its economy.
Honestly, Karnataka could be on its way to become a Bimaru state too, if the politics isn't cleaned up at this juncture. The likes of Deve Gowda and his kin will make the state what Lalu and his kin made of Bihar. I pity the Biharis, the state which was historically on the fore front of Indian politics/education and culture has been ruined in a couple of decades, and their locals dont have a say in how their state should be governed.. :(
