Leave it as it is but instead of your focus on political clap trap deliver the services Australians want done efficiently and effectively.That Canberra has low unemployment is not a bad thing as the capitals main business is govt and if it cant look after the people that live there what hope is there for the rest of Australia. That the average wages there are higher is due to the fact that there is a large workforce of well educated people concentrated there to give effect to the Acts of Parliament and associated regulations.
If you feel you are not being productive in earning your high wage you could leave and join struggle street elsewhere.
