this renewed push for centrally-planned economies is not going to end well. we're currently dealing with the outcomes of the poorly-sourced Modern Monetary Theory and this is the same throwback to "hey, just plan everything out from a central place there are efficiencies being wasted!". It has the veneer of science and logic, just like Marx did, except it ignores basic realities and papers over the actual science by not showing its math and not accounting for things we know to be true -- like the fact that people like stuff.

Here's a basic example from their article that becomes hilarious, where they argue for shifting away from capitalism to models that don't really exist or are akin to Donut Theory (not really showing their math):

>Balancing the national economy will require new macro-economic models that combine economic, financial, social and ecological variables. Models such as LowGrow SFC (developed by T.J. and P.A.V.), EUROGREEN and MEDEAS are already being used to project the impacts of degrowth policies, including redistributive taxes, universal public services and reductions in working time.

>But these models typically focus on a single country and fail to take into account cross-border dynamics, such as movements of capital and currency. For example, if markets are spooked by low growth in one country, some companies might move their capital overseas, which could adversely affect the original country’s currency and increase borrowing costs. Conditions such as these posed severe financial problems for Argentina in 2001 and Greece in 2010. International cooperation for tighter border control of capital movements needs to be considered and the effects modelled.

So we have to find the right model or create one and shift away from capitalism and all will be well -- the ones listed are not exactly ready for primetime. But when you do that, if you're the only one doing it everything will collapse because capital and resources will go towards more competitive markets. They're basically telling you that even if it did work, it would never actually work unless everyone did it at once, hence this could only happen in a constrained system where all the larger countries were in full cooperation. Which isn't realistic without force. Which brings us full circle to Marx, but don't worry the taking over with force for your own good is only temporary!

This is not a real answer to anything, and they're actually telling you it themselves.
