Arvind Adiga's The White Tiger is an excoriating portrayal of the post- colonial realities of India. It is a moral biography of his protagonist who makes a long journey from a remote village in Bihar to the city of Bangalore. This presents how the proletarian yahoos are exploited by the capitalist houyhnhnms in post-colonial capitalist India. The novelist projects India as a divided nation into 'Rich India' and 'Poor India', and attacks her economic miracle and rise as a global power. In the self of a sociologist, psyche of an economist, and spirit of a humanist he focuses the crude realities of India's socio-economic growth. Focusing the realities of shining India he attacks her failure to establish democratic socialism. The capitalist mission of the rich helps them to exploit the poor that makes India a faltering nation. The novelist is serious about the condition of the poor due to India's rise as a global power. India's alround progress without eradicating poverty is the authorial concern that disturbs the sociologists, politicians, economists and policy makers. He believes that this is a kind of internal colonialism in which his protagonist desperately fights for his existence. The rise of the rich and capitalist class in metropolitan cities and progress in industrial and IT sectors do not define the real progress of India. The protagonist's movement from his native village to Delhi and Bangalore is a soul searching mission in an emancipatory zeal. While the protagonist murders his master it sounds like the story of crime and punishment but the nemesis reveals that the subaltern protests only to end his subalternity. A postcolonial reading of the novel reveals the difference between common man's imagination of India during freedom movement and her growth as a global power in the recent times
