I was in Delhi last week and Delhi has come up very well ... the reason .... because it has its own state govt. But other metros (inspite odf people living here paying huge taxes) has pathetic infrastructure ... the reason ... the rural development has to happen in their states otherwise they lose the elections for trying to develop the metro. So if all the metros has their own state govt then people living in metros will get the value for the tax money. The central govt can concentrate on the development of the rural India. Hope I have a point here ...
