Charlie Stross brought this idea up on his blog recently; what does a post work-for-pay world look like? What would you do if you had a home, food, and health care as a basic right? Could we even get there with our current basic cultural value being that if you don't work, you have no value?
If I had a home, food and health care as a basic right, what I would do? Raise my child with undivided attention, care and love. Try to make his environment a happy, safe and stimulating place. The kind of stuff that modern society apparently considers optional, or not valuable at all.
