The Narendra Modi government’s sudden demonetization of `500 and `1,000 notes in November 2016 failed to put a dent in the black economy but caused untold hardship to hundreds of millions of Indians. Corrupt businessmen, corrupt politicians, and corrupt members of the executive (bureaucrats, police and the judiciary) are responsible for controlling the black economy and enabling its growth. It has crippled the country’s economy for a long time to come. In this book, Arun Kumar, the country’s leading authority on the black economy, tells us why Modi’s gambit failed. He shows us how the problem can be rooted out, provided the government has the political will and determination to act.
