Felipe Luther, 37, a scholarship student at Pontifical Catholic University of Rio (PUC-Rio) who also works as a street-sweeper, walks along the shore of the beach picking up rubbish that sunbathers leave on the sand on Arpoador beach in Rio de Janeiro, Brazil, May 11, 2021. In 2017, Luther got a full scholarship to the social sciences program at the Pontifical Catholic University of Rio (PUC-Rio), a private school that has minted central bank presidents and movie stars. Luther, 38, had previously passed up college for work to support his family, including a job sweeping streets with the municipal cleaning agency since 2009. "Many students like me start working when they are very young," said Luther, who comes from humble roots in the northern reaches of Rio, more than two hours from campus. "This reduces the time and structure they need to be able to compete with children of the elite." REUTERS/Pilar Olivares SEARCH "BLM OLIVARES" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES
