Twinklytroll, everyone's circumstances are different. I lost my job when pregnant. It made sense to stay at home. DH's hobby is his job and he earns enough for us to survive (we're by no means well off).
I see DH's career as his luxury whilst I'm stuck at home sometimes. I'm happy in my upaid work, DH is happy in his. The luxuries and sacrifices are different depending on circumstance. DH doesn't see him working as pressure, he actually sees me staying at home as pressure.
Unless you're wealthy, SAH isn't a luxury but a cost saving sacrifice. A choice between working to pay a childminder or cutting out the middle man and being the childminder yourself. Especially for two parent households who earn just over the amount for help, but just under the amount for luxury.
I recently got offered a job, and turned it down, even though I'm actually looking for work, would like to work etc., because it would COST me financially, and would cost my time. Its frustrating. Next year will be different as both boys will be at school so at least childcare will be less.
I am not complaining, I would have chosen to SAH regardless. But it was also the most sensible choice as a family, even though it was pretty disasterous from a 'decent job' for me. I'll re-train, start over, there's time.
