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.[7] 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".
