What sort of society are you striving for in Oz? Seems people want to tear down the salary of anybody earning more than they are?
Remember, people having their incomes slashed, destroyed or removed altogether has a compounding and terribly deleterious effect on society and the domestic economy as a whole. The effects are pernicious and far reaching. Those on low six figure salaries tend to spend a lot of their cash on things that prop up the local economy, eg: home renovations, restaurant meals, etc.
One individual's job loss or income downgrade means you are next in the firing line.
And unions ain't the enemy.
