Paul Krugman starts blog at NYT -- politics and economics of inequality

The name was somewhat familiar and had a vague, good feeling about it. He seems to hold policy mostly accountable for economic inequality. The graph tracks the 10% richest Americans' percentage share of total income. That bottom trough is the lower 30s% when there was a middle class and much less inequality. It lasted from about 1942 to 1982.
