I'm not speaking from a position of ideology. I'm describing the world based on a scientific understanding of human motivation.
Sorry if that's incomplete.
I didn’t take your position to be one of ideology (although your position certainly isn’t based on science); I’m pointing out that you responded to the parent’s concerns about meeting everyone’s needs (I.e., “running an economy”) with some stuff about human motivation and the caveat that human motivation will only do the job if basic needs are already met.
And deciding which things are "needs" and which are "wants". We'll never agree on that, so no level of basic subsidence will ever seem like enough.
