Outside class hours, Kim Kyung-wook delivers meals on foot to apartment blocks near his university in eastern Seoul, while constantly checking his phone to trade stocks, cryptocurrency and used Nike sneakers.

That probably won¡¯t help him land a well-paid job when he graduates later this year, but Kim says such side hustles are a ¡°smarter thing to do¡± in the face of increasingly bleak job opportunities and an expanding income gap under President Moon Jae-in.

Kim is one face of a lost generation that many see emerging as the key voting bloc that could swing next year¡¯s presidential election. Already, he and voters like him helped the main opposition party triumph in April by-elections for mayor of Seoul.
