I do not intend to start a South-North debate but here are a few facts why South India fares a tad better than the North

1.Obvious stated first..Better literacy rates ( Kerala 93.9%, Andhra 91.1%..compared to national avg 75%) means more people are educated and hence is better informed about the causalities.

2. Presence of regional poltical parties forming governments  in the likes of CPI-M in Kerala; AIADMK,DMK in Tamil Nadu, TDP in Andhra. You do not want to mess up the only state u have the sphere of influence on :)
