BUENOS AIRES (Reuters) -Argentina's libertarian President-elect Javier Milei must appoint a head of a central bank he previously pledged to burn down and task a minister with overseeing one of the world's most pressured economies. Milei's chosen team will shape policy in South America's No. 2 economy in the years to come as the outsider contends with inflation above 140%, net reserves in the red and myriad capital controls. The country, in which four-in-10 people live in poverty, is also the International Monetary Fund's largest debtor.
