NEW YORK – Concern about economic inequality is in the air almost everywhere. The issue is not inequality between countries, which is actually down in recent decades, thanks in large part to higher growth rates and longer lifespans in many emerging countries (especially China and India). Rather, the focus nowadays is on inequality – sometimes called income disparity – within countries.
One reason is that the problem of inequality is real – and growing worse in many places. In recent decades, wealth and income have become more concentrated at the top – the so-called 1% – while real incomes and standards of living for the poor and middle class in many developed countries have stagnated or declined.
