Nithin Kamath, co-founder of Zerodha, has reignited the debate on the relevance of gross domestic product (GDP) as a measure of economic progress. In a recent post on X, he traced GDP's origins to the 1930s, when economist Simon Kuznets was tasked with evaluating the economic collapse during the Great Depression. Kamath highlighted that Kuznets intended GDP to reflect welfare rather than mere output, warning against including expenditures that do not improve people's well-being. Over time, GDP has transformed into a production gauge, counting all spending equally, regardless of its impact on quality of life. Kamath criticized how GDP can rise even amidst environmental degradation and increased healthcare costs, emphasizing that it fails to account for genuine improvements in human welfare. He cited recent criticisms from UN Secretary-General António Guterres and economist Diane Coyle, who pointed out how damaging activities can inflate GDP figures. As the world faces significant economic shifts driven by artificial intelligence, Kamath's remarks contribute to a broader conversation about the adequacy of traditional economic indicators in measuring progress.
