When the public in general are prepared to pay to watch nurses doing their jobs for 90 minutes, with a tea break half way through, (both live and televised) and buy nursing related souvenirs (replica nurses uniforms etc). When nurses become internationally recognised media stars and feature in Nivea (spit) adverts. When nurses' opinions are sought by news outlets on subjects totally outside of their job zone, and they get paid for them. When nurses get a percentage cut of their value when transferred from A&E to Maternity, then maybe, just maybe, the pay gap between Premier League footballers and nurses will be reduced slightly. Don't hold your breath waiting though.
