You've touched on some good points and missed some big ones, as the comment thread demonstrates, but don't let the money specialists beat you down too much, AA. You are on the right track.

It's not about money, in the long run of physical nature. It's about usefulness and value, and how these are determined by Life itself, not by spreadsheets and advertisers.

Whether robots do the labor or humans, the value of the labor lies in what the laborer adds to the future of its offspring (or in the case of robot, its perpetually repairable self). Ownership feudalism is all about convincing people to create value and usefulness for owners, regardless of the quantitative needs of the laborers. Sure, we have very complex and elaborate schemes to bury this extraction behind cultured habits, but even the most fair cooperative democracies are city-state support systems that really only return a minimum amount of value: most primarily return violence or threat of poverty downhill while shoveling value onto an upward running conveyor belt.

You will find that every attempt to increase the amount of payback is denied with the excuse that your plan will make the 'life giving' Authority shut off all access to life.

What did we ever do without gods, eh? Even more to the point, what did we do without marketing?

Modern civilization is great and impressive, but a little more digging into the price inflation aspects and damages being done to our children's future environment won't add up any better than the war costs, luxuries, roads, airports and sports stadiums of this supposedly "sustainable" Economy of Stupid based on a hope that magic money will find resources, prevent birth defects and cancer or convince the rest of the world that rape is love.

Taxing profits needs to start by taxing the prophets of anthrocentric profits.

What are people for? Once robots can do whatever we think that is, why keep people ?
