According to Paul Streeten [101, the relationship between
poverty eradication and reducing income inequalities is still an
unsettled question. He mentions empirical studies of eleven countries.
In ten of these countries, poverty and inequality move in the same
direction, both increasing (Brazil, Mexico, Indonesia) or both declining
(Korea, Taiwan, Sri Lanka, Costa Rica, Yugoslavia, China and Israel).
The only exception is perhaps Kuwait, where poverty (of Kuwaiti
citizens, but not of the large group of immigrant workers) has been
reduced, while inequality has increased (explanation: oil
wealth).
