Sadly this couldn’t be further from the truth in reality. I’ve never understood where this touring myth came from but it’s just not the reality. I know artists who are B listed on radio 1 who literally stack supermarket shelves overnight. You’d think someone getting significant airplay on the nations most important station for new music, selling out mid size venues and with decent streaming figures would be able to at the very least focus on performing, but they have a day job in an office, then go stack shelves at night. This is the reality for musicians in 2018.
As @anon48905947 has said, the issue is primarily that, as with most things in life the deck is stacked against those at the bottom, Universal made more money from music than ever last year, but it’s all through backhanders from the likes of Spotify which never trickles down to the artists themselves.
