Why Are Savings Rates So Low? It's The Income Disparity

From Naked Capitalism:

Andrew Dittmer, who was an important collaborator on ECONNED, sent me pdfs of the notorious Citigroup Plutonomy reports for leisure reading. Michael Moore highlighted these two research reports (2005 and 2006) in Capitalism: A Love Story .

On the one hand, the authors, Ajay Kapur, Niall Macleod, and Narendra Singh get some credit for addressing a topic surprisingly ignored by mainstream economists. There have been some noteworthy efforts to measure the increase in concentration of income and wealth in the US< most notably by Thomas Piketty and Edmund Saez. But while there have been some efforts to dispute their findings (that the rich, particularly the top 1%, have gotten relatively MUCH richer in the last 20 years), for the most part discussions of what to make of it (as least in the US) have rapidly descended into theological debates. One camp laments the fall in economic mobility (a predictable side effect), the corrosive impact of perceived unfairness, and the public health costs (even the richest in high income disparity countries suffer from shortened life spans). The other camp tends to focus on the Darwinian aspects, that rising income disparity is the result of a vibrant, open economy, and the higher growth rates that allegedly result will lift help all workers.

Yet as far as I can tell, there has been virtually no discussion of the macroeconomy effects of rising income and wealth disparities, or to look into what the implications for investment strategies might be.
