With enough efficiency gains, people would prefer to do things and give things away for free. There are costs to putting prices on things. With enough efficiency gains, people would get more subjective benefit from not pricing something than by pricing something. We see this in action already, like with Bill Gates. It costs him more subjectively to not do all the charity work he does. This is showing us that Bill Gates gets more benefit out of helping people eradicate a disease than he does the amount of his monetary wealth it costs him. Not only does Bill Gates not want to make more monetary wealth off of eradicating disease, but the subjective benefit is so great that he prefers to spend monetary wealth for his subjective emotional-type gains.

Something I think worth thinking about.
