>Ergo, the goal of automating a society is not to automate 100% of the work, but to automate (100-V)% where V is the amount of voluntary work available.

Isn't that the economic reality rather than "the goal"? And doesn't this also put an shade on your original argument that it is "the will. A culture change is needed"?

I haven't worked for 20 years but I work in certain automation, and from what I've deduced it is rather that the V in (100-V)% is quite high, and then there's W = a x V (a is an positive constant) that specify required labour, specialization & investment for automation; which is almost always lower in supply than "voluntary work available".
