"Most people do not have a need to hire 3-4 people. Growing up it was common to have a maid who helped with household chores due to the absence of amenities like a dish washer or washing machine. As these services become available there is no need to hire folks to do such work."

I completely agree with this. When I was living in New York, I rarely felt a need to "hire" someone to do stuff for me. Apartment didn't get dirty so easily. Clothes didn't get dirty so easily. Very easy and convenient access to laundromats. Dish washer at home. Easy access to fairly high quality groceries. Lots of places to eat around which had healthy food options at reasonable prices (relative to your salary). Anything you wanted could be ordered online.

If on top of all this, you just hired a maid by the hour, for a couple of hours, to come clean your house like once in two weeks, you didn't need anything else.

Here in India, it's hard to get by without a maid. Clothes get dirty fast, house gets dirty fast, no laundromats, no dishwasher, no space to keep a washing machine at home, poor availability of healthy food options, groceries sellers have bad quality of food and vegetables so you need to spend time picking them out, supermarkets have massive checkout lines etc.
