My husband barely earned a living wage, and I was still a SAHM while the children were little. We lived carefully and cheaply but very happily, and the children thrived. It's all about your priorities. My priorities were spending my children's most formative years trying to pack in as much love, learning, talking, and fun as possible. Of course that impacted our finances, but for me, it was worth it.
Interestingly, most of my children's friends have fairly well-off, working parents, and now they're teenagers they all want to come over to our house because they have terrible relationships with their own parents, who have no time for them or their interests, and frankly seem to see them as an inconvenience, and be very negative towards them. But that's anecdotal.
I understand wanting to defend sending your children to nursery during the working week, and lashing out with the implication that I must be lying about my parenting; that's fine. But it's very silly to act as though putting your children into nursery full-time couldn't be validly seen as a harmful thing to do, easily on par with smacking. That's my point.
The outrage seems a little hypocritical and overblown, and smacks of people echoing current social norms without thinking about what they might be doing now that could be frowned on in another decade (and as with most things, probably didn't really cause any harm on a demographic level).
