Seems very unlikely that Republicans are just going to 'go away', and not present a barrier to these very well-intentioned plans. There is a need for capitalism and growth, and I fear a communally minded society is not going to happen in the way so many people might want it to - they do not have control of the system as it is and cannot assume that a four year voting cycle will enable them to do this.

You need practical, actionable strategies and I don't think 'degrowth' (eg any form of deindustrialisation or similar) or indeed MMT (which in many ways also expects miracles and a morally perfect demogrophy) is going to be possible. The US already looks like it will owe over $1 trillion servicing it's debt this year - far more than Biden was able to afford for the IRA or even the defense budget, which kind of puts MMT as I understand it in the shade.

As I set out in my book Scheduled Collapse - Who is Blocking the Transition to Net Zero and Why, effective answers do exist but they are being undermined by vested interests. Some monetary policy changes (green interest rates, for example) are being advocated for by a wide variety of stakeholders, including the French president among others, but this is probably the level of structural change that we can hope to achieve across the board, at best.
