Hear about the free-market policy that the Institute of Public Affairs didn't like? Congestion pricing. It's a terrible idea, an IPA "research fellow" argues today for News Corp, portraying it as "elite class ... agenda of centralisation and densification".

A congestion price, this week urged by the Grattan Institute and immediately rejected by the NSW and Victorian governments, "hits the least wealthy hardest", according to the IPA. As a result, "the suburban working-class would be forced either to pay extra to get to work or to cram themselves into unreliable, already full trains."

Well, the unreliable bit is certainly true in Sydney, where each day commuters wait to learn which minor problem will bring the entire network to a halt -- something for which no one, anywhere, ever seems to be held accountable.
