The median working American earns something like 60k. Part time working adults are around 24k.

People might not have 20k in the bank, but if most are doing a part-time employment's worth of work which could be replaced by a machine, it would make sense on paper.

Granted, people aren't rational. Anecdotally, my partner and I probably could be hiring out some of this currently, but we choose not to as we don't want to have to work around a cleaning service's schedule. I think we'd be more apt to buy something which we own, have control over, always does things in the manner we'd like, doesn't have to work around our messy lives/schedules, etc.
