Higher taxes seems like the easy no-brainer solution to get more public funds to improve services. But it isn't that simple.
Look at how many women who operate on a fine balance of the benefit of work, relative to the cost of childcare and the difficulty of balancing work and life responsibilities, for whom an increase in tax may be the tipping point to withdrawing their labour completely.
And those who continue to work as they approach retirement and decide to pull the trigger early because more is raked by the government.
People with desirable skills, our police, healthcare workers and teachers, who are often poached from Australia, etc look at their increased tax burden and decide it isn't worth it.
How about those people who are consequently disincentivised from taking promotions or growing their business because it's more tax and trouble than it's worth?
It may seem like a moral imperative to increase tax on those who earn more but it has to actually work, not just make you feel like it's working.
