George Megalogenis is an amiable, straightforward writer, and as a good journalist he doesn't bury the lede. Indeed his argument is basically summed up in the back cover blurb of this Quarterly Essay: Australia's current model of an open, liberal market economy, with its political emphasis on the state always cutting taxes and running surpluses - is no longer coping with a global capitalist crisis. Therefore Australia needs to invest in education and infrastructure, and to pay for it corporations should pay more tax, and governments should stop being afraid of borrowing. Oh yes, and we need to tackle inequality and property bubbles as well. Climate change is always something of an afterthought is these types of essays.
Megalogenis is a talented articulator of prevailing conventional wisdom, so for him to write an essay such as this suggests CW is shifting. As to how to achieve it though, George is still despite himself in thrall to the 'reform' narrative of Australian politics - whereby heroic leaders such as Paul Keating seize us by the scruffs of our necks for our own good. However for reasons set out by Liberal pollster Mark Textor, whom George quotes, this approach (if it was ever real) is unlikely to work now. That is because the state, having divested itself of its responsibilities to look after voters under capitalism - no longer has loyalty from those voters. Hence the rise in relative political volatility in Australia (not that we are that unstable compared to some places).
So 'reform' in the future will have to shift from an elite to a popular project - which means said reforms may not always be what the conventional wisdom thinks is good for us.
