Go back to your favorite Wikipedia and look up where Amartya Sen was born, but maybe for some reason he didn’t know that there was a famine in his native Bengal in 1974, even though he wrote several scientific papers and a book on the subject. So write a book, it will be a smash hit, believe me.
By the way, Amartya Sen argues, for example, that almost unbelievable inaction combined with the wrong economic policies of the colonial government that led to market failure caused the Bengal famine of 1943. In his book, he clearly presented how politics, governance, and (in)action are important in humanitarian crises like famine.
But therein lies the root of the problem, for to the deeply racist British colonial government, not only for Churchill, the Indians were an inferior beastly race, more animals than humans, and simply did not care for their lives, especially if the actions of the colonial government in order to saving the lives of Indians meant that there was less looted money in their pockets.
