ven the Treasurer Scott Morrison hasn't made the case, apart from to say that pushing up the GST would be a bit like turning back boats, and that if the proceeds were used to cut income tax, fewer people would suffer bracket creep.
Turnbull began removing the GST option on Friday. He said the first question was whether he wanted to raise more tax overall. He did not. The second was whether the upheaval of a higher GST and the compensation it would necessitate would produce "a productivity benefit, a growth dividend that justifies the trouble". He left the clear impression it would not, an impression backed up the Treasury's discussion paper.
