Cool, you guys have already covered my thoughts about government being orthogonal to (but intertwined with) who owns factories. The discussion on efficiency is interesting too. Notably this line:
then you just need to give them something of equivalent value for the service which is made by the org you work for.
If we only ever exchanged things of "equivalent value" we would never have progress. Progress only arises when we get more value out than we put in. For instance: You spend a week making a shovel so you can dig a well in 1 week, instead of taking 4 weeks to dig a will without a shovel. Also, a good economic trade is where both parties increase their own value by making the trade*. An
ideal trade is one that increases the
wealth of both parties.
This relates to efficiency - economic efficiency isn't "making the most profit" it is "getting the most value out for the least resources in." This definition of efficiency is more broad than the one that is focused on profit, because you can expand 'value' to include things like "long term stability." So in that sense, our current systems (at least in the "west") are only locally efficient, not globally efficient: you can get a lot of value for some resources, but only in a particular sensitive environment (see: COVID-19, natural disasters, a fire at a factory producing components that are a bottleneck for the overall product for some simple examples).
As for "public ownership" of production and social systems: as I've stated elsewhere in this forum, I think what we have to do is not have something like UBI which is kind of arbitrary, but really have a universal public
dividend. This dividend would not be some arbitrary fixed monetary amount, but would be a share of the overall produce of some "sufficiently large" jurisdiction. It would be something like every taxable entity is taxed at, oh, maybe 50%. A portion of that tax is used for government, and the remainder is divided up per-capita. This way the "rich" can still have personal benefit from their higher income, but there is guaranteed "trickle down" because their profit is explicitly shared with everyone, rather than by "market forces."
*This is incidentally how "late stage capitalism" happens: a single trade may be "good" in that both parties gain value. But if the trade is wealth for a service, or a durable good for a consumable good, then this is how capital gets concentrated: I trade rights to my land for some food. I gain value, because I can eat. But I have lost wealth - I have lost the ability to produce food.
