Emerging in the UK in the 1960s and ’70s, David Hockney, David Bowie and the members of the Beatles and Queen have become some of the world’s most-known artists. Many of them grew up in working class families, and their success stories are sometimes invoked as proof of a functioning meritocracy. New research, however, finds that there are half as many creatives from working class backgrounds in the UK now (about 8%) than there were during the supposed “golden age of mobility” in the decades following World War II.
