Before you call southern states 300 years forward compare development level in Western UP and Northern karnataka or telengana in AP.
Karnataka is not just Bangalore and Mysore it also has Bellay Raichure , Bidar which are poverty striken and development level matches to that of eastern UP and Bihar.
Incidences of dowery related harassment is equally and even more widespread in Andhra and Karnataka. On the other hand if you want to compair urben infrastruture Noida is definately better then Bangalore. All these stories of South being lightyears ahead are fanned by regionalism and chuvanism. For your kind information highest growing states in India are Hariyana and Gujrat which is almost equal to China (10 %). Will it be correct if Gujrat or Hariyana starts saying that southern and northern states are a dragging factor ?
development level in rural western utter pradesh , Northern MP , eastern rajisthan is any day better then drought prone interiar karnataka, TN and Andhra. Its time southerners wake up to the fact that growth just does not mean city based growth fulled by IT and BPO it needs to be more broad based and equitable.
In my openion Gujrat presents best development model as it is generating a large blue coller jobs apart from white coller ones.
Disclamer : I am not a Gujrati and I am based in Bangalore
