**A TIMES AND NEW YORK TIMES BOOK OF THE YEAR 2022** An explosive exposé of a firm whose work has made your world more unequal, more corrupt and more dangerous. McKinsey & Company have earned billions consulting for almost every major corporation in the world - and countless governments, including yours. Shielded by NDAs, their practices have remained hidden - until now. In this propulsive investigation, prize-winning journalists Walt Bogdanich and Michael Forsythe reveal the disturbing reality. McKinsey's work includes ruthless cuts to the NHS, troubleshooting for Big Oil, incentivising the prescription of opioids, executing Trump's immigration policies (the ones that put children in cages) as well as advising some of the world's most unsavoury despots.
