I listened to NHK radio program in English.
It was an interesting article.
This is that Technology & Business: Responding to Your Specific Needs - New Housekeeping Services
(I don't know how long we can listen to it on the net.)
Here in Japan having housemaids is not so popular (among not the upper class), of course I can't afford to hire a housemaid either.
However looking back to about 50 years ago, not only the upper class but also landowners or some middle class people used to hire some housemaids. (Well, my grandaunt was single forever, and worked as a professor at a women university, and she hired a housemaid, which was also her friend, my great grand parents hired some housemaids because there were lots of people to live together.)
Now, it's completely different.
And now we face the population decline because of the declining birthrate, though increasing the number of senior people.
So for senior people they have no one to help them. It means they might need someone who do house chores instead of them. However the people in their 60's or 70's are not used to accept other people who do house chores or ask something to other people .
For young people in their 30's or 40's, probably after 10 or 20 years, it will be usual that a couple work "outside" together, (I think doing housework at home is a kind of work.), so they might need a house made, but what such a housemaid does? Do they live in such a big house?
Such couples don't have free time in weekdays, so they can't go to bank or post office to do fill out paperwork. However housemaids won't be able to take care of such paperwork because these days it's really difficult to deal with personal information.
---- sorry I can't put together my thoughts. (even though in Japanese).
Anyway the article was interesting.
