In Monte Python’s Life of Brian we were introduced to the “People’s Front of Judea”, which was “one of many fractious and bickering independence movements, who spend more time fighting each other than the Romans”. The segments featuring the Front were very amusing. It was humour but redolent of the sort of historical struggles that have divided the Left over the centuries. In Australia, the history of the Communist Party, for example, is one of many factions, splintering into new parties and leaderships after disputes about Bolshevism, then the Communist International and Stalinism, then the so-called “imperialist” war by the Allies against Nazism, then Krushchev’s revelations about the crimes of Stalin, then the Soviet invasion of Hungary, then the split between the Soviet Union and China and the rise of Mao, then the Soviet invasion of Czechoslovakia, and so on. This sort of division is mirrored around the world on the Left side of politics and struggle. I have been reminded of this history in recent weeks as the ‘war’ against Modern Monetary Theory (MMT) has been ramped up from so-called progressives. However, this ‘war’ seems different to the sort of internicine struggles that have historically bedevilled the Left. We now have all manner of strategies emerging, ranging from classic Association fallacies to ridiculous claims that MMTers perpetuate ‘anti semitic tropes’, and on to plain invention, a.k.a. straight out fabrications or lying. There is no real attempt to embrace the body of work we have created over the last 25 years. Quite the opposite – the ‘critics’ haven’t an original thing to say about the substance of MMT. They have instead decided to smear us with increasingly hysterical assertions. Which raises the interesting question for me – what is driving this aberrant behaviour? Fear, a sense of irrelevance, jealousy, Brexit, spite, … what? I have conjectures but no real answers.
