> With almost 8 BILLION people on this planet soon, not everyone can meaningfully contribute People keep saying this, but why is it true? Why can't you just have 4 billion people making boutique food for the other 4 billion who are making boutique clothing in return? Why can't you have 8 billion people making TV shows for each other while robot housekeepers keep them alive? Mental health care alone would seem to me to be an almost infinite market in need of labor. Is there some economic law that defines an upper limit on how much work there is to be done? I see seemingly infinite undone tasks around me.
