No, his argument is that the average human needs this standard. also, it is a model, it is by definition simplified.

His argument is the average hmuan needs this standard.. so we can cut "unnecessary production" and it will be fine. I'm arguing that he cant label things unnecessary because hes found a standard wealth level he thinks is good enough. It wont work as an approach because humans require a diverse range of inputs to live happy lives and that requires a diverse and dynamic production economy.
