A vital and timely investigation into how the consulting industry has made its way to the heart of our economies and governments - and what to do about it

There is an entrenched relationship between the consulting industry and hollowed-out, risk-averse governments and shareholder value-maximizing firms. Mariana Mazzucato and Rosie Collington show that our economies' reliance on companies such as McKinsey, Boston Consulting Group, Bain & Company, PwC, Deloitte, KPMG and EY stunts innovation, obfuscates corporate and political accountability and impedes our collective mission of halting climate breakdown. The 'Big Con' is possible in today's economies because of the unique power that consultancies wield through extensive contracts and networks - as advisors, legitimators and outsourcers - and the illusion that they are objective sources of expertise and capacity. The Big Con weakens our businesses, infantilizes our governments and warps our economies.

Mazzucato and Collington expertly debunk the myth that consultancies always add value to the economy. With a wealth of original research, they argue brilliantly for investment and collective intelligence within all organizations and communities, and for a new system in which public and private sectors work innovatively for the common good. We must recalibrate the role of consultants and rebuild economies and governments that are fit for purpose.
