While I don't mean to hurt Indian sentiments, possession of nuclear weapons and aircraft carriers is hardly an indicator of the state of development of any country.
Any reasonably sized economy can own them even if half the population is starving. That is the power of aggregation. What matters is per capita income. Can India really afford to buy a laptop for all its children? $100s is almost three months salary for a primary school teacher in many parts of India. And there are hordes of qualified people willing to work at those wages, if the government gives them the job. Yet there are so many vacant posts, and if what I hear is right there are so many schools without any teachers at all. Why is it?
