I can understand why libertarians might favour a flat tax on superannuation contributions and on ordinary income. I disagree vehemently with that position, but it’s logically coherent to me. Personally, I favour a progressive tax on both of those things, and I think that position also makes sense. What isn’t coherent to me is the idea that we should tax ordinary income in a progressive way, with higher income earners paying a greater proportion of their income in tax, but we should tax super contributions with a flat tax. How does that make sense?
In late 2010, we set an all-time record for the Australian economy: nearly 66% of people aged 15 and over were either employed, or were actively looking for work. To put that in perspective, the labour force participation rate has averaged 63.2% since 1980.
