>The USSR was also powerhousing out of being a backwards as hell pre-industrial hellhole. Other countries will also require considerable growth that will have to come from somewhere.
True. But their mistake was that they didn't switch to consumer products.
>There's other forms of growth and development that aren't just pulling resources out of the earth and adding them to society.Developing collectivization and improving access to already existing assets effectively adds to people's consumption capacity without significantly adding to the demand for production.
Regarding collectivization: The important questions are what and how deep? Because mining and steel production isn't sensitive to economic plans. It's basically a bunch of STEM-problems.
Agriculture is a totally different thing, as it relies on tacit and knowledge. Just the different soils can you devote entire libraries to. And still not say the last word. A good grazing field for sheep and goat such as steep rolling hills may not be suitable for cows, as they may break their legs there. Optimize farming is something that should be done in concert with the farmers and play to their vested long-term interests.
>There's also the fact that vast amounts of material are ripe to be recycled but simply aren't under capitalism because it's often cheaper to simply extract raw resources on lines already designed for that. Obviously there will still be some amount of growth and development, there is not a necessity for maintaining zero-growth all the time. The important point is that we can do it in a sane, safe, and reasoned manner, instead of the utter chaos of capitalist forced development at all costs.
Yeah, a lot of things are impossible to repair by yourself and so on. But there's plenty of branches where the state intervention regarding the goods-as-such are a bare minimum. Consider synths. There's the voluntary MIDI-standard. And then there's general standards such as conforming to the electric mains, general consumer protection and pattern protection. Disregarding this, synts doesn't exists as any state is concerned. And the second hand value of them are often so high and the second hand market so vibrant that by itself it is a safeguard against waste.
