why do we employ fellow human beings to come into our homes and make them do jobs that we ourslves are not willing to do?

I have never understood nor do i respect parents who hire maids and let them wear pyjama looking outfits to look after thier children-if i was to pay someone else to lok after my son, i wld want and treat her well so that hse looks happy and is cheerful company for him-"do unto others as you want them to do unto you"
