Scott Morrison and Josh Frydenberg want you to know that if the economy tips into recession and the budget surplus they not merely promised but claimed had already been delivered fails to materialise, it's the fault of coronavirus.

It's not their fault -- despite the fact that they refuse to show economic leadership of any kind.

Yesterday, as share markets around the world slumped, the PM and the Treasurer called a media conference to say exactly that: it won't be their fault, even though they don't propose to do anything and certainly won't undertake any fiscal response to help the economy.
