I must introduce you to Marshall Brain's Robotic Nation essays.

The short of it: in a fully automated society, it is simply infeasible to have 100% (or even 50%, with most jobs moving into the service sector) employment.

Thus he proposes a $25,000/yr/person stipend funded from a combination of sources, including high marginal rates on new tax brackets for multi-million-dollar corporate salaries, various sales taxes, and the full reallocation of social spending in almost all other areas.

The result would be a complete elimination of poverty, the stigma of welfare, wage slavery, and the social security solvency problem, leading to a "supercharging" of capitalism via massive increases in consumption and ultimately "true economic freedom".

I find this proposal very appealing, yet lacking in other core respects; e.g., those countries and entities with the greatest access to natural resources will continue to be the root sources of growth and power, and as money is simply a tool for distributing wealth, it inevitably adapts to reflect the availability of wealth. Maybe he's also assuming energy from pervasive nuclear fusion? Moreover, extreme consumption and growth also translate into extreme environmental devastation. Increased economic activity invariably decreases our quality of life, at the very least in so far as our natural environment is concerned.

I was waiting for him to mention gift economies, but he seems to love the profit system too much to accept its fundamental infeasibility in the long term.
