“Kepler undertook to draw a curve through the places of Mars, and his greatest service to science was in impressing on men's minds that this was the thing to be done if they wished to improve astronomy; that they were not to content themselves with inquiring whether one system of epicycles was better than another, but that they were to sit down to the figures and find out what the curve, in truth was.”

-- Charles Sanders Peirce (1877)

Inequality in the world economy is dominated by a common trend, with turning points around 1971, 1980, 2000

The most-likely explanation is changing global financial regimes.

Key Global Finding

Page 14: A presentation at the International Labor Organization United Nations Geneva, Switzerland April 16, 2012 by James K. Galbraith Inequality and Instability

Brown: Very large decreases in inequality; more than 8 percent per year.

Red Moderate decreases in inequality. Pink: Slight Decreases. Light Blue: No Change or Slight increases Medium Blue: Large Increases -- Greater than 3 percent per

year. Dark Blue: Very Large Increases -- Greater than 20 percent per

year.

The oil boom: inequality declines in the producing states, but rises in the industrial oil-consuming countries, led by the United States.

This broad picture of the world economy from the standpoint of inequality measure suggests that the “super-bubble” was also, for most of the world’s population, a “super-crisis.”

The super-bubble came to a peak in 2000-20001.

The period since then was marked in the United States by efforts to keep the bubble going, in part through aggressive efforts to relax standards, which may be described as the growth of a “predator state.”

This led to the corruption of the financial markets whose collapse produced the great crisis.

Page 24: A presentation at the International Labor Organization United Nations Geneva, Switzerland April 16, 2012 by James K. Galbraith Inequality and Instability

Pay inequality in the US depends mainly on economic conditions, especially the unemployment rate.

Income inequality in the US depends mainly on the stock market, and is driven by top-level incomes in highly concentrated small areas.

For example: Manhattan, Silicon Valley in the 1990s, Washington DC in the 2000s
