Doctors expected to cut their earnings as running costs increase

There should be no freezing of the rebate as has been signalled by the federal government. Which profession or trade in the country would be prepared to take a 14–19% cut in their earnings (as proposed by this government) when the running costs of their businesses are increasing. 

For the pollies to provide an example, how about they start with themselves and take an 18% cut in their salaries and freeze that
for the next five years?
