Vance vice president at Trump's. What does that mean? [COMMENTARY]

J.D. Vance became known mainly through his 2016 book "Elegy for Bidoks. Memoirs of household and Culture in Crisis. This book describes his experience in youth, where in retrospect he tried to analyse the social and economical problems of the working class. Here we are talking about the alleged Rust Belt, a highly industrialized and mining state (Michigan, Indiana, Ohio and Pennsylvania), which since the late 1970s and 1980s began to experience a crisis as a consequence of recession and competition from abroad.
