Why is the government going ahead with a coal price cap when economists and even their own Cameron Milner (8/12) are saying it will not work? Does the Prime Minister’s media adviser not alert him to what is being printed?

The proposed cap on coal and gas prices is to lower the consumers’ energy bills, but will it cost the taxpayer billions of dollars in compensation payments? Is this a case of robbing Peter to pay Paul?
