Speaking on ABC's The Business, Joe Hockey, who served as treasurer under the Abbott Coalition government, said voters would only accept fiscal pain when they 'feel really ill'.
'There's going to have to be a crisis now. There's going to have to be a financial crisis,' Hockey said. 'People will only take the medicine when they, you know, feel really ill about it. And I think this is coming right across the world.'
His comments came less than a day after Jim Chalmers addressed an Australian Financial Review gathering, where the current treasurer lamented the state of political incentives. 'Power is much more effective right now in the distorting and blocking than the building or reforming,' Chalmers said.
Hockey knows firsthand the difficulty of reform. His first budget in 2013 abandoned election promises and introduced sweeping spending cuts and user-pay fees, provoking a backlash that forced the Abbott government to retreat from most measures.
He pointed to a structural crisis across the developed world: income tax—the largest source of government revenue—is about to be exceeded by welfare payments. 'The problem is governments have no restraint when it comes to expenditure,' Hockey said. 'They're so focused on populism, they'll spend whatever it takes to get re-elected.'
The fragmentation of party loyalties has worsened the problem, Hockey argued, as governments chase minority votes rather than pursuing sustained reform.
Earlier this week, Chalmers released the seventh Intergenerational Report, outlining the long-term challenges of delivering a balanced budget.
