Oh yeah I get this.
I'm a sahm. I own half the house which has a small mortgage and high value (500k ish). I have my own pension that we still pay into. All of our savings are split into accounts in individual names so in effect I have immediate access to half that he doesn't, and vice versa and we've a years salary in there. We both have critical illness cover, death in service benefits and life insurance. Our wills leave everything to each other. I'm married.
I don't have a degree, but I have twelve years of a decent career with five at low senior management level.
I'm also a full time carer to one of my children who has ASD, which we didn't plan for obviously. But most people (in RL) don't know that because she's a fabulous masker, very cognitively able and hold it together until she gets home when she just explodes. My youngest is still under school age. I'd always planned to go back to work when she started school but my eldest needs will probably make that impossible.
My word. Mention I'm a sahm and all you have is cries of 'you'll be screwed if he leaves'. Erm, no I won't. We would need to sell the house (of which I'd get half) and I'd need to find a job. Which wouldn't be a breeze, but it'd be perfectly doable. My brain hasn't dissolved just because I've been at home for five years!
I have lost count of the number of times (on here and in RL) that I've had the head tilt, the insinuation that I'm lazy, the assumption that I must have not had a career worth bothering with if I was willing to give it up, that I'm probably a bit thick. I have even been asked if my eldest is 'like she is' because I'm a sahm, and asked if I think that she'd 'be ok' if I'd just put her in nursery from a young age instead. Erm, that's not really how it works!!
I truly do not judge working mothers. I think everyone should do what works best for their own families. I don't think nursery harms very young children, nor do I think it's particularly beneficial before about age 3. Even though I'm at home, mine use their 15 hours in a preschool at age 3 because after that age I think the socialisation is good for them in preparation for school. I've also had comments about that. What could I possibly be doing at home for those 15 hours a week, hey?! I don't need them, I don't work! But they need them.
I do think that the people who are condescending to sahms are the ones that are coming at it from a place of not having the choice. There are probably very few women who could happily and easily afford not to work, but choose to purely because they want to or are worried about not contributing society. Anecdotally every working mum I know would either not be able to afford not to work, or would have to accept a significant lowering of a very nice lifestyle standard in order to do so. And they don't want to. That's fine. But then don't disparage other people because they do have the choice or are able to easily make a different choice to you.
When you're being snippy about a sahm, ask yourself this - could you make the same choices if you wanted to without you being a) unable to afford to survive or b) really changing your lifestyle in a way that you wouldn't want? If the answer is no, then your scorn is probably coming from a place of jealousy, rather than concern!!
