I really do think working mothers resentment to those who sah is quite sad.
You personally are not paying for us to stay here. I'm not sure why it bothers you so much.
I have 4dc's (3 under 4 years) They go to nursery 5 mornings a week. I have the choice to,
- Do housework.
2, Go to the gym, for a run (5 miles this morning)
3, read a book (i've got 2 on the go)
4, crochet (doing bunny baskets for the 3 little ones)
5,mn, fb, twitter, internet in general.
6, go back to bed.
But after that time, it is relentless.
I live in a large 4 bed detached with 2 and half bathrooms, 2 receptions, utility, large garden etc that I can have spotless, but looks like a bomb has been through it 24 hours later. (probably the age of the kids) The washing is a daily occurence ( and drives me mad.) I even take the bins out.
My dp works away a lot (9 days away back last fri night, now gone again till thursday)
I've worked f/t and looked after my eldest and ran the house, as a single parent.
My dp gets out of bed, see's to himself, walks out the door, goes to work, and then comes home to a clean house, (not necessarily tidy everyday though) clean clothes, ironed, food cooked from scratch 9 times out of 10 (takeaway if i'm lethargic) and happy, taken care of children.
I would have killed for that when i was getting up at 6am, to get dd1 to the childminder for 7.30am, to run the gantlet on the motorway every day, work 9 to 5, and get back for 6pm, to still have to do everything i do now. (although admittedly the house was smaller)
He did the whole, I have it harder crap for a while, until I left him for a 1 week experiment, and the house was a complete state, no-one had any clean clothes etc.
He's never moaned since. 
I may work when the children are all at school, I may not. We are not rich, barely over national average for one wage between 6 of us, big mortgage, but we make sacrifices. It is a choice.
If you make a different one, that's your prerogative, but I don't think it should be turned into the eye rolling, pathetic creatures, can't work and do house work tut tut.
