It's the fact you assume that mothers who go to work when the family could make cut backs and survive on one wage do so because they either:
- Value their jobs more than their children, or
- Value "expensive lifestyles" more than time with their children.
I think what you'd find if you paid attention to what others were saying is that they do value their children more than anything else in the world.
For example, we could just survive on one salary. Either of our full time salaries. But what that would mean is that my time (or DHs) with DD rather than working would come at the cost of basically everything fun. We'd have to let one car go, but that would mean that DH (for arguments sake) would have it every day because of how far away he works. There's no public transport to get him there without the commute being several hours. That would mean DD and I would be limited to wherever we could walk to, because we'd not have enough money for public transport for fun.
We'd only have very basic food. There'd be no baking, because ingredients are expensive.
There would be no paid for activities. No swimming lessons, no gymnastics, no dance class.
We can't downsize because we're only in a two bed anyway. Unless we all lived in a one bed or a studio. We could move somewhere cheaper but then we'd be further away from DHs job again, and from anything we could do within walking distance.
New clothes/toys/colouring stuff would only be from birthday or Christmas presents. From other people.
If something in the house needed fixing, we'd have to go without even more basics.
You talk about going without to be able to stay at home. I'm not entirely sure you know what that actually looks like. You sound incredibly privileged.
