For decades fiscal mismanagement and corruption have made Argentina an economic backwater. But Macri, the new President, has foreigners and Argentines alike expressing optimism about the country again. Macri, the former governor of Buenos Aires, won a very close election last fall against a ruling party dominated by cronies of Argentina’s past leaders. Among his first acts: reintegrating Argentina in the global economy by pledging to repay debts on which it had defaulted. The country “is fast becoming a model to its neighbors,” says Richard Haass, president of the Council on Foreign Relations.
