Mate. Lucy has gone missing for weeks on end. She certainly doesn't work 9 hours a day 5 days a week.
Not that I want to get in on the sad pocket counting with you guys
But the argument closer to reality is probably that she can and probably does earn the nation's median salary off the 5-10 days she does work a month. As opposed to working the standard 20+ white or blue collar days a month (where she probably wouldn't even make the median based off her CV).
Putting her on parity with a 300K salary is moot.
Under the same logic Premier League refs get a 1-1.5K commission on top of their base salary for an afternoon's work. We don't consider them to be 1M salary equivalent because at 3pm on a Saturday they are, in that moment, earning about 5 bills per hour.
