> For now, planning works, but it works for them, for the rich capitalists and their profits, not for us and our needs. The next step is for us workers to organize and take the companies into our hands. And to lay the foundations for a society oriented towards need rather than profit.
I think this is something of a mistake. The best use of resources isn't nearly the biggest problem facing a planned economy. The biggest problem, currently seen clearly in both russia and ukraine simultaneously, is that when a planned economy crops up, for war production or socialist reasons, there is a great temptation for those involved to do corruption, at whatever level they can. falsify reports, change production numbers, all sorts of crimes to accumulate power over the flows of resources, such that that power can be leveraged to trade for other things.
The real problem to be solved is a social one. How to make the watchers who watch the watchers? Corruption can in principle never be fully prevented entirely - enough people believing that corruption goes unpunished and any system will fall. But building a system convincingly self-sustaining enough that everyone can't quite be sure that others aren't checking their work (and in a more positive framing, one where people feel good work is both expected and rewarded), one where people can be confident corruption will be found, will pay dividends in people policing their own behavior.
This goes for most economic systems as well.
