He veers between a state regulated market and pragmatic decriminalisation on drugs, they're different approaches. His defence and foreign policy approaches are just as muddled.
Neither does Zack appear steeped in green economics (as personfied by E F Schumacher) but muscular fairly mainstream Keynesianism. Always like to inform Zack's left supporters that Keynes was a member of the Liberal Party.

He's not just a particularly hubristic Keynsian. He's anything that sounds like it means he can spend a lot without raising taxes. He's MMT as well.

It's nonsense. Hopefully James Meadway can knock some sense into him.

As I understand MMT its spend and tax. Taxation is raised as a method of halting rising inflation. According to advocates who are lousy at politics even if the economic theory is plausible. It is a kind of round the houses deficit spending.

Taxation is raised as a method of halting rising inflation.

Once upon a time, we had a thing called "Purchase Tax". The rate varied depending upon what it was that you were purchasing. If the economy showed signs of overheating, it was raised; when it was slack, it was reduced. It was a method of controlling the economy.

As an example, it probably did more to kill the British radio and television industry than anything else; for example, in a boom period manufacturers would step up production of their TV sets - and then when the Chancellor looked at the economy as a whole and inflation was rising, up would go the PT, leaving manufacturers with warehouses full of TVs they could no longer sell because they suddenly became very expensive indeed.

Sounds very worthy but misguided. A green policy might be to tax cheap disposable goods out of existence in favour long lasting repairable ones.

The Purchase Tax was a tax levied between 1940[1] and 1973[1] on the wholesale value of luxury goods sold in the United Kingdom. Introduced on 21 October 1940, with the stated aim of reducing the wastage of raw materials during World War II, it was initially set at a rate of 33.33%.

The tax was subsequently set at differing rates dependent upon individual items' degree of "luxury"[2] as determined by the government of the day.[3]

The 33.33% rate was increased to 66% for cars costing over £1,000 in 1947 and this rate was extended to all cars from 1951. In 1953, it was reduced to 50%.[4]

In connection with the accession of the UK to the European Economic Community,[5] the Purchase Tax was abolished on 2 April 1973 and replaced by the Value Added Tax (VAT), charged on most goods and services, which is currently charged at a rate of between 5 and 20%. https://en.wikipedia.org/wiki/Purchase_Tax

There was a 'luxury' rate of VAT for a while, wasn't there? I've got an idea that it was either lower, or not much higher than today's standard rate.
