MIT: Get over yourself. I taught in rural Cornwall, so actually, being able to employ a 'good Nanny' was not in the equation, given the amount of kids on free school meals therefore poor; and finding a preschool could be challenging and out of the economic reach of many people. We don't all live in cities fgs, or have highly paid jobs. As for £200 to go to the Hairdressers or Harvey Nics; most of the mums of my students would have told me to get real! That was probably a third of their take home pay.
I didn't say that ALL kids were like that, as clearly some weren't; but those that were posed a problem in school. I didn't say either that kids aren't well-rounded, but some have few social skills because their parents aren't around to teach them. I can't comment on Swedish/Danish kids as I taught British kids.
The point I was trying to make is that I saw many cases of kids not being cared for, or left to their own devices because both their parents worked, so there was no-one at home for them. No-one knew what they got up to, or even where they were after school, which causes problems. I make no comment about them being single mums or not; many were in nuclear families, some in reconstituted families, and some single parent families. I also don't think it matters if the mother is 'knowledgeable' (I presume you mean with letters after her name) or not. One of the best Mums I've seen is one of my students who had her son at 13 (family abuse), came back to do her GCSEs, and now works as a cleaner at school so she doesn't claim benefits. Her lad is always clean, laughing and loved.
I feel it is a shame that many women feel forced to go back to work because they have to; because the government gives you more money in the form of WTC if you do, which creates a client state.
I have no problem with working mums, I went back to work when ds was 6 months old, on a part time basis, until he was 5, when I retrained as a teacher, and then worked full time. However, this meant long days at school for him, from 0750 to 1730, and latterly to 1830, so that I could work, whilst my dh worked abroad, and only got home once every six weeks. Now I don't work, our relationship is better; he likes me being there when he comes in, and getting my full and undivided attention, and my dh is happier too, as I am easier to live with. There is a trade off with mums working, and we have found that we function better as a family if I don't work.
Whilst the Armed Forces have us posted abroad, I am not going to go back to work, apart from examining GCSEs once a year to earn the fees for my MA.
And, before you say I am sponging off the state because the government pays my husbands' wages, I'd point out that he paid enough in tax last year to cover the net salary I received as a teacher just below the top of the pay scale.
