You know, it doesn't really matter to the original point. If the middle class is doing okay or if it's struggling, either way household androids and more generally less labor scarcity are exactly the kind of thing that will improve the situation.
Except it will do literally no such thing. The working classes exist because of scarcity of labor, not despite it. Adding labor to the pool dilutes the value of a unit of labor (supply and demand). Only the tiny minority of individuals who own and control capital are positioned to capture any benefits accrued by increased availability of labor.
