Income and consumption inequality

'But consumption numbers, too, conceal as much as they illuminate. They can record only that we have spent, but not the value—the pleasure or health—gained in the spending. A stable trend in nominal consumption inequality can mask a narrowing of real or “utility-adjusted” consumption inequality. Indeed, according to happiness researchers, inequality in self-reported “life satisfaction” has been shrinking in wealthy market democracies, America included, suggesting that the quality of lives across the income scale are becoming more similar, not less.'
