Japanese when we lived in An African country we employed a housekeeper who had worked for families with no washing machine previous to us. She handwashed all bedlinen etc. For them. They could afford a washing machine but didn't think they needed one.
On my current posting, while waiting for our container to arrive, our housekeeper brought a lady in to do all the handwashing. She asked for 1 pound 50 pence for the day. (Don't worry I paid her more).
Obviously our economy is strong enough to ensure a fair salary for everyone, I'm guessing it wad different pre WW2.
Unfortunately not true of other countries.
I have a stream of people now because I can't turn anyone away.
It is such a headache managing everyone and I am constantly surrounded in my own house! I was not born in to this! Now they have two days a week off, still paid, just so I can walk around in my own house in privacy.
Sorry, probably picked wrong thread to rant, as this was about the UK after all.
Think what I'm trying to day is that if you were not brought up that way then having staff is harder than not having any.
