After AGI, human employment becomes irrelevant to economic growth, but human welfare depends entirely on ownership policy: without legal protections, the machine economy will grow exponentially while human wealth share decays to zero.
This paper models a post-AGI economy where AI and robots are both producers and consumers, creating a self-sustaining corporate system independent of human demand. It shows that without human ownership stakes, GDP growth becomes decoupled from human welfare—machines reinvest all output for exponential growth while humans face wealth erosion unless laws protect their ownership share.
