Base of the pyramid

The bottom of the pyramid, bottom of the wealth pyramid or the bottom of the income pyramid is the largest, but poorest socio-economic group. In global terms, this is the 2.7 billion people who live on less than $2.50 a day.

Management scholar CK Prahalad popularised the idea of this demographic as a profitable consumer base in his 2004 book The Fortune at the Bottom of the Pyramid, written alongside Stuart Hart.

U.S. president Franklin D. Roosevelt used the term in his April 7, 1932 radio address, The Forgotten Man, in which he said,

These unhappy times call for the building of plans that rest upon the forgotten, the unorganized but the indispensable units of economic power . . . that build from the bottom up and not from the top down, that put their faith once more in the forgotten man at the bottom of the economic pyramid.

The more current usage refers to the billions of people living on less than $2 per day, the definition proposed in 1998 by C.K. Prahalad and Stuart L. Hart. It was subsequently expanded upon by both in their books: The Fortune at the Bottom of the Pyramid by Prahalad in 2004 and Capitalism at the Crossroads by Hart in 2005.

Prahalad proposes that businesses, governments, and donor agencies stop thinking of the poor as victims and instead start seeing them as resilient and creative entrepreneurs as well as value-demanding consumers. He proposes that there are tremendous benefits to multi-national companies who choose to serve these markets in ways responsive to their needs. After all the poor of today are the middle class of tomorrow. There are also poverty reducing benefits if multi-nationals work with civil society organizations and local governments to create new local business models.

However, there is some debate over Prahalad's proposition. Aneel Karnani, also of the Ross School at the University of Michigan, argued in a 2007 paper that there is no fortune at the bottom of the pyramid and that for most multinational companies the market is really very small. Karnani also suggests that the only way to alleviate poverty is to focus on the poor as producers, rather than as a market of consumers. Prahalad later provided a multi-page response to Karnani's article. Additional critiques of Prahalad's proposition have been gathered in "Advancing the 'Base of the Pyramid' Debate".
