I thought this part was interesting. It's a trope to claim that "the Kenny Report has never been implemented" but he demolishes this:
Significant changes have been introduced since Judge Kenny made his recommendations nearly 50 years ago. Firstly, capital gains tax on the sale of land achieved the purpose of the “betterment” tax recommended in the Kenny report – since 2008, the rate of CGT has increased from 20 per cent to 33 per cent.
Secondly, the “right” to planning permission on zoned land and to compensation in lieu have been abolished.
Thirdly, let us not forget that development levies....were recommended by Kenny and have been in place for more than 20 years.
