"Most problems are due to inadequate policies and poor institutions," Malik said. "It's not innate that people have to suffer so much."
He points to the insecurity of employment in most of the developed world, amid a global "race to the bottom" by big corporations seeking the lowest wages in the poorest countries.
Nearly half of all workers worldwide are in insecure or informal employment, while 842 million, or about 12 per cent, of all people go hungry, he said.
Government budgets are shrinking, affecting their ability to provide social structures, as the rich evade taxes and the poor have little to give, he said.
The issue of inequality applies even to countries in the very high development index group, when their score is adjusted for internal inequalities in health, education and income.
The U.S. falls from five to 28 on that list, South Korea drops from 15 to 35, and Japan falls from 17 to 23.
