Remember the television show “Hazel” or “The Brady Bunch” and the maids?
I'm not sure how many mid 20th century families had "help", but on TV it seemed pretty common.
It seems to me that if you have money for a maid, I think it puts you above Middle Class.
If you ARE a maid, it puts you below Middle Class.
My definition of Middle Class is that you have enough time and money to take care of your own stuff.
I don't know too many people who are really "independent" in the old style. People pay others to solve their problems for them, or else they live with the problems.
Or Family Affair?
