Chao's lyrics provoke his audience to think about immigration, love, living in ghettos, drugs, and often carry a left-wing message. This reflects Chao's own political leanings—he is very close to the Zapatistas and their public spokesman, Subcomandante Marcos. He has many followers among the European left, the Latin American left and the anti-globalisation and anti-capitalist movements. Chao is a founding member of ATTAC. Punk and reggae historian Vivien Goldman commented of his work, "I was writing about Good Charlotte and The Police. They adopted the trappings of punk. They aren’t bad groups, but the punk aspect is more manifested by somebody like Manu Chao. He's one of the punkiest artists out there I can think of. It's an inclusionary spirit that is punk."
