Essay Assignment on Income inequality and growth

Topic: Consider the following text from June 15, 2015 of The Economist concerning income inequality and growth:
“In 1975 Arthur Okun, an American economist, argued that societies cannot have both perfect equality and perfect efficiency, but must choose how much of one to sacrifice for the other. While most economists continue to hold that view, the recent rise in inequality has prompted a new look at its economic costs. Inequality could impair growth if those with low incomes suffer poor health and low productivity as a result, or if, as evidence suggests, the poor struggle to finance investments in education. Inequality could also threaten public confidence in growth-boosting policies like free trade, says Dani Rodrik of the Institute for Advanced Study in Princeton.”
