If general-purpose humanoid robots become available at ~$20-30k, then every household in America will have at least one.

The credit payments on that robot will be immediately worth it, even to lower income families because it frees up so much time — it's your housekeeper, chef, nanny, doctor, dog walker, all in one.

I mostly agree with this, but imho low-income households will be more sensitive to how it directly monetizes & services that credit through rental. 
the one thing in that list that matters more than anything else is medical & childcare services, which assumedly would be shared among many households.
