JUBA, South Sudan — James Ukongo Uber, 13, is an orphan who works as a shoeshine boy to pay for his uniform, paper and pencils and other fees to attend school. He raised $1 from panhandling to buy black polish and a brush to "polish big people's shoes."It’s a desperate life, but James is one of the lucky children in this poor, war-ravaged East African nation. South Sudan is home to the world's highest proportion of children without an education. Half the school-age population — more than 1.8 million children — doesn’t attend school, according to UNICEF.
