Recent political economic developments in Guatemala exemplify the broken promises of top-down “globalization” and “multiculturalism,” which have instead produced “global apartheid” (Besteman 2018) and “multicriminalism” (Speed 2016). Youthful countercultural Guatemalans, who call themselves callejeros, engage in their own bottom-up projects of globalization and multiculturalism through their participation in street cultures. Callejeros resist, critique, and enact different forms of violence in the process, sometimes challenging the racist-patriarchal-capitalist status quo, other times reproducing it. My study of callejeros' everyday triumphs and struggles provides insight into the culturally and politically productive capacities of marginalized young adults in cities of the Global South.
