If you could provide reliable electricity and water for 300 million people for $74m ($0.25 per head) then you might have a point, but it's not really a lot of money for a country as large as India.
So true. $75 million is not a lot of money for India. The Prime Minister's Office just spent $50 million on latest equipment for his bodyguards (secret service detail). ONE Indian company just signed a deal with the Nepal government to spend $1 billion for ONE hydro project in Nepal. And it is nowhere in news in India.
Not very many. And for how long?
If you look at it from another perspective: providing jobs for the scientists and all the industrial manufacturers with that money probably did a lot better in that regard.
