“Mr Grudnoff said it was time for the entire tax system to be reformed, including looking at applying GST to private health insurance and private school fees, among other items.”

These are not the words of a “Senior Economist”, they are the words of an ideology driven hack. His ridiculous proposal will drive people back to using public education and public health, driving up the costs of maintaining both, and further burdening the tax payer for zero improvement in services. By every metric, his suggestion is how you make things worse!
