Yes indeed, We can and we will be a superpower. But not before 2020.. It would be much before that.. I would say by 2015...
All we need to do is ensure that we focus continually on improving the BOP, and the trade deficits have reduced drasticallay. A large number of people are still below poverty line. However the Standard of living has gone up overall. There is a clear evidence of improved infrastructure, Higher literacy percentage, Reduced unemployment levels.
Now since we are heading in the right directions, what needs to be watched out for is development of rural areas and control on corruption at all levels from top to bottom. This would ensure availability of the right amount of funds at the right place, for the right people and at the right time.
