The Turnbull government is apparently keen to undertake more reform, in this case applying to the welfare system. This weekend I saw a couple of media reports, unsourced but apparently based on material supplied by Social Services Minister Christian Porter, based on the “alarming” projection that welfare payments will rise from $154 billion to $270 billion in a decade, more than can be accounted for by inflation and population growth.
A huge dollar figure makes for a scary headline but not for sensible analysis. The prosaic facts underlying this projection are
(a) Welfare payments are dominated by the old age pension
(b) The value age pension increases in real terms over time, since it is linked to earnings
(c) Even allowing for an increased age of eligibility, and more reliance superannuation, the proportion of the population eligible for the old age pension is unlikely to fall
Put these facts together, and it’s virtually certain that the welfare bill will grow broadly in line with national income (usually measured by GDP), and therefore will outstrip growth in population and inflation. Indeed, a quick check suggests a compound rate of growth of about 6 per cent*, almost exactly in line with nominal GDP (assuming 3.5 per cent real growth and 2.5 per cent inflation).
The government’s proposed reforms appear to involve attacks on recipients of welfare in the popular media sense of the term (Jobstart, disability benefits and so on). But the only ways in which the growth rate of the welfare bill can be held much below that of GDP are
(i) Freeze the real value of age pensions, as has been done to Jobstart since the 1990s; or
(ii) Reduce access to the age pension, either by further raising the access age or by tigntening means and assets tests.
* Porter’s briefing apparently suggested 7 per cent, which I can’t replicate. Feel free to check.
