A comment first: yes Mr Swan, your fiscal rule is strict: if there are additional expenditures, you bring in a new tax to meet them.
That is as strict as it can get.
But whether that is responsible or not, or a good fiscal policy approach or not, is another matter altogether, isn't it, Mr Swan?
It is not too difficult for people to see it at least is a very lazy approach, no matter how you dress it up and spin around.
PS: maybe Mr Swan meant another strict fiscal rule: to only allow school to use the BER funding for building school halls and or libraries, irrespective what they need most and how effectively those school halls and or libraries contribute to those schools education needs.
Of course, it was wastage, as most people have realised.
Further, the pink batts scandals are worse than whether the insulations are effective or efficient or not, it still costs taxpayers money now to just fix up the messes left by those programs.
