My sister is a nurse. The nurse to patient ratio is different in every countries. In Hong Kong, despite what the news says, the ratio is like 1:10-16, whereas it is about 1:4-6 in the UK. So if nurses get more salary in HK, it is probably because they have longer shift hours and the workload is more crazy.

As an artist, you have a basic salary, and then the more work you do extra, then more income comes in. If Lisa is only doing a few episodes a month, then she will get the basic salary which she perceives as low. But when she does more commercials, guest stars in show, ribbon cutting events, then she will get more money.

It is not fair to compare the salary of a nurse to an artist because the latter can get bonuses whilst the former has capped salaries.
