You don't need capitalism to deliver anything, you need competent organization and people who will do the organized work. Tell me how many of the people working in those supply chains (truck drivers, ship mates, Amazon warehouse workers) think the system is working for them under capitalism. Joint stock / pooled risk and profit, and abstraction of ownership in a way that mirrors cash as an abstraction of value, were innovations for sure. Other innovations or adjustments maybe difficult to make in today's brownfield world.

My take is that central planning's problem wasn't one of where the planning took place, it was one of data quality (freshness, accuracy), inadequate data, and problems in the agenda for using it. Integrated macro- and micro-planning will still suffer from the central-agenda issue, depending on the motivations and means of the planners. But coordination up and down, for purposes that are not exclusively for the generation of cash, seems worth exploring.

Discussion today in one paper about prescribed burns in Yosemite held up due to air quality laws, but no mention of jailing Mother Nature for the air quality violations of a major forest fire. I suspect the long-term sustainable carrying capacity of the Earth for humans is rather less than the number outstanding today, but starve and die seems worse than options we could engineer if we wanted to. Fight in battles and die will be a lot of them too if things swung the wrong way.

We need economies that allow nations to distrust each other, and in the USA at least allow every individual to distrust every other. Socialism seems to work best for those who buy into a social contract and the USA is losing those people left and right, egged on from within and its adversaries.
