The former minister for environment, Greg Hunt has made the following statement when discussing the safeguard mechanism (see "Federal election 2016: Greg Hunt denies carbon tax by stealth", The Australian, May 25, 2016): "Our policy is not budgeted to raise a single dollar of revenue. By contrast, Labor's carbon tax raised more than $15 billion in just two years. This was a major hit on the economy and increased electricity prices." Do you agree with this assessment of the carbon tax policy? Provide at least two reasons why this criticism of the carbon tax is misplaced.
