AMERICA’S FISCAL largesse during the pandemic has fuelled not just economic growth but also, more surprisingly, a lively hip-hop niche. Over the past two years musicians have released no fewer than 30 different songs referring to the government’s stimulus cheques, known as stimmies. “Yeah, check, I need a stimmy.
