It's amazing how diplomats are seen as harsh slave drivers paying a pittance and being served by minions as if they were royalty. Unless you've done it, you can't imagine. I did it for 25 years in 9 different countries. Even my own family presumed it was all sequins and caviar !
As OP has said, it is totally normal for a diplomatic family to employ local house staff. It's not a perk of the job, it's something expected. The whole system is unheard of in Europe these days. It's more like Downton Abbey but actually with less staff! We adults dressed ourselves!
Thanks to nannies, I brought up 4 kids from ages 3 months through 18yrs in Africa and Asia. When I started, my first son was 3 months old. He had a live-in daytime nanny Mon/ Saturday and a night nanny. They knew more about babies than I ever did. I also had a housekeeper, a cook and kitchen boy, a sweeper, a laundry lady, a seamstress, 2 gardeners, 2 drivers and 3 armed security guards. After I had son No. 2, I had an extra 3rd nanny who shared the daytime work. They usually all got on well but in case of friction, came to ask for help. Similarly, though I was only 30 they came to me to help with all kinds of things particularly the women with family problems.
It all sounds like the life of Riley but it was a bit more complex. The largest staff we ever had was 18 people and I could and did cover all their wages with my pay as a half time English teacher. There was a trickle down effect too. My staff had their own staff at home who also had their staff at home. Obviously on a much smaller scale but their salaries were sufficient for them to do that. It was like that in every country we worked in. We once did some calculations with them and established that their salaries were in fact looking after almost a hundred people, young and old. Over and above salaries, we paid all medical expenses and contributed to the cost of weddings, funerals and celebrations.
I apologise for being so long-winded but I just want to add a bit of context.
I could be accused of not being 'there' for my kids as much as I could have been but when you aren't the one cooking, cleaning, doing laundry and all the normal housewifey things, you have much more time on your hands to be Mum.
We had evening events in Embassies and such every couple of weeks but it was usually only an hour or 2 hours so when the kids were little they were asleep and when they were teens, they were delighted to have us out of the way!
