So Ritchie says Heseltine is right in saying this:
He’s right. Supply side reforms do not work.
And Heseltine is calling for a bonfire of regulations. Which is a supply side* reform of course. For it is reform of the supply side.
Can Ritchie read?
* No, supply side does not mean just lower marginal tax rates. It means reform of the supply side. Privatising BT was a supply side reform, deregulating the airlines was a supply side reform, changing planning permission would be a supply side reform.
