Fair pay is a widespread issue.
One of the reasons I left medical practice, for a more assessment and reporting type role, was that after paying all running expenses I wasn't earning much more than a Senior Constable for a 40 hour week and still had increasing unpaid paper work to do to communicate with bureaucrats and helper organisations. I eventually worked out there was a better way to go.
GPs can form large groups to afford to pay Practice Managers to do all this for them, but that means the local GP disappears in favour of supermarket type practices you have to drive to. More specialised medicine doesn't work this way, so you congregate in subsidised specialist centres at private hospitals near the CBD, and the outer suburbs get neglected. I did consider taking a salaried job at a public hospital several years ago and found out that while they have vacancies the state government in Victoria doesn't actually supply the funds to fill them. [I ran into that in SA back in the 1980s too.] NSW and QLD are constantly advertising jobs at good salaries.
As I have said elsewhere, pollies and government bureaucrats think they are the only ones who should get decent pay, and that they, and only they, should get paid "commensurate" with the few top flight executives in big business.
Interestingly, in the UK, after 54 years of screwing doctors, they reached crisis point of staff shortages in 2003 and put doctors salaries up 35%. I think teachers and nurses do much better there now too. It took the UK from 1949 to 2003 to wake up to the fact that what is happening now in Oz doesn't work - eventually you can't get anyone to do the jobs.
