Writer of popular textbooks on macroeconomic myths, N. Gregory Mankiw has just put out a paper – Defending the One Percent – which is due for publication in the Journal of Economic Perspectives. The paper presents a narrative about the shift in the US personal income distribution (sharply towards higher inequality) since the 1970s in terms of rewards forthcoming to exceptionally skilled entrepreneurs who have exploited technological developments to provide commensurate added value (welfare) to all of us. As a result, rewards reflect contributions and so why is that a problem? In other words, the “left” (as he calls the critics of the rising inequality) are wrong and are in denial of reality. That view is unsustainable when the evidence is combined with a broad understanding of the research literature. Ability explains the tiniest proportion of the movements in income distribution. Social power and class, ignored by the mainstream economics approach, provides a more reliable starting point to understanding the rising inequality.
