I'm really amazed by the responses which describe SAHP with children as being "quiet" or "pottering around", on which planet is this and can I join you there?
I know plenty of well-off SAHMs, and it is anything but peaceful, quiet, pottering around etc. Just the regular drop-off and pick-ups which your average SAHM with two kids does makes a taxi-driver look tame. never mind the shopping, meal prep, time management, homework, appointments, arghghghg.
When I had a 9-5 office job, we used to joke with colleagues who had kids that Monday morning was OUR bliss time, arriving in a quiet, well-ordered, clean office, adult quiet talk, limitless coffee, kid-free zone.
Do you simply dislike your job? then maybe search for another job: there's always shortage of cleaners or homecare work, no office politics, and some cleaning companies are set up so you can manage your own time. Bonus: lots of cultural diversity!! As these jobs are frequently taken on by poorly-paid, female immigrants!
On a lighter note: Did you ever read Agatha Christie- remember that Lucy whatshername character in 4:50 from paddington, who gave up her high-achieving maths job to become a "Domestic", mosty because of reasons you mention? LOL
Do you simply dislike "work"? Then get politically active in some Basic Income for all Citizens movement - it won't happen in our lifetime, but maybe future (first world) generations won't be saddled by this pesky nuisance called work...
