This ignores diminishing returns of additional labour and consumption. If we reach the happy situation where robots are providing us with the things we need for a good life almost automatically, why would we continue to work ourselves to the bone for additional goods and services that won't increase our happiness much? Most people would rather just work less. In fact, our current level of economic output is enough to give every household a comfortable life, even if we worked substantially less. Unfortunately the system is structured to maximize labour time, keep us economically insecure, and use us all as grist for the capitalist mill, rather than maximizing leisure time and quality of life.
