Let me know if any of these sound appealing:
The Credit Theory of Money
It's kind of fundamental, but I don't think (forgive me; I've not quite caught up on all the past episodes yet) it's had a lot of emphasis in the past.
The Non-Bank Financial Sector
I'd still like to talk to someone with experience working in finance (suggestions?). This would be a natural follow-on from the credit theory of money. i.e. public money has value because it's a future tax credit → bank money has value because it is a promise to provide public money on demand → loan contracts, bonds, stocks, etc. have value because they are promises to provide public money (usually via bank money) under particular terms over a period of time → financial derivatives have value because they promise some financial asset, or combination thereof, at some point in the future under terms that look not entirely unlike gambling.
Frank Stilwell and Political Economy
I'd just like an excuse to chat with Frank (via Zoom or whatever, probably) before he kicks the bucket. As well as being the co-founder of the Department of Political Economy at Sydney. Just before he retired he put the lectures for the introductory unit online — it's been a long while since I watched them, but I recall them being rather like John Harvey's Contending Perpectives. He was also a co-founder of Sydney Politics in the Pub, which I used to enjoy in the 90s and early 2000s. He's not really got his head around MMT, as far as I can tell, but he knows as much as anyone alive (with the possible exception now of Steven) about the challenges of teaching heterodox economics in Australia.
The MMT Lightbulb Moment
Last year, fellow MML student Steffi in Adelaide turned up to a tutorial all excited and announced that she finally worked out what MMT was all about, and why it was so important (she must have enrolled more for the ecological side of things). It was so lovely seeing somebody so soon after that penny drop. It would be nice to talk to a few MMT students/activists/advocates/whatever about their lightbulb moment, how it changed their perspective, etc.
The Myth Behind Modernity
It seems to me that every system of government proposed since the Enlightenment has one thing in common: the vision of a utopian prehistoric, pre-government past, which informs a prescription of the natural order that society should adhere to, and then justifies any sort of policy you like based on your preferred (and necessarily fictional) prehistoric utopia. It's the foundation of Liberalism, Anarchism, Communism, Fascism, and certainly Neoliberalism and neoclassical economics. The fantastic In Bed with the Right podcast did an episode on natural law philosophy recently, and I immediately thought "Ooh! RadioMMT should do this!" Not so much the serious philosophy side of it, but the fact that in our current moment, natural law thinking is so deeply embedded in both neoliberalism (eg. the "natural" rate of unemployment, inflation, interest, etc.) and the MAGA neo-fascist reaction to it. Why does this way of thinking persist, despite the fact that as a matter of definition, it is necessarily the case that everything in human society is "artificial" rather than "natural", and always has been. And despite the fact that we know that all of these prehistoric utopias are ahistorical, evidence-free, and nothing like them has been found in any society we know of. It is a tremendously silly way of thinking, yet we are all guilty of thinking like that from time to time.
Vertical Fiscal Imbalance
Ray "CityNerd" Delahanty did an episode on this about the US situation. Why does an allegedly egalitarian country like Australia put up with a situation where the quality of your public services depends on how wealthy your neighbours are? The mainstream frame the problem as state and local government lacking sufficient power to tax; we know it's due to state and local government lacking the power to spend.
United Australia Party: A Very Serious Policy Platform Review
A canary yellow brochure was dropped in my letterbox recently, about something called the New Deal. (Where have I heard that term before?) I think it deserves some MMT-informed scrutiny.
