It is a different mindset and they are happy with what they are doing. I come from India where there is a ton of that labor. When I lived there, I had a couple of full time house help, supplemented by cook etc as needed. They had plenty of time by themselves. They would genuinely just zone out when they had free time, even significantly long. THey liked the easiness of the job, and the fact that once it is over, it is just over. No need to think about tomorrow, take your work in your head etc. A lot of the world's people are like that, maybe even a significant majority.
