She probably signed away her right to stop working for him, and is now stuck working $2 per hour! It can't be that she's a free person able to choose to work for a given rate. She must be a victim!
Not really. It doesn't take much effort to manage properties like this. Most guests on Airbnb don't want negative feedback as the author mentions, so they make an effort to leave the place as they found it. The person managing the property is probably not the same one cleaning it. She sources her own cleaning team most likely, and very may well have 60 or so properties under her wing. @ 80 properties & 200 bucks per month, after paying the cleaning team, she is pulling 12000 without lifting a finger. Also, I would be willing to bet she does not report all that income.
