Getnet "Getu" Marsha shines shoes at Charlotte Douglas International airport. He left Ethiopia at age 14 as a political refugee. He's been in the U.S. since 1992. About 13 years ago, he decided he wanted to give back to his hometown of Addis Ababa. He recruited a network of adults to care for street children there, and each month, he tries to send back 10% of his earnings to support them all.
