I believe children should be taught a whole lot more in schools other than subjects like maths and English, life skills should be taught, confidence building, body image, boundaries, and acceptable relationships, only then will women stop finding themselves in dead-end abusive, love lacking relationships where children are being brought up in, to no doubt repeat the cycle all over again!
They do - it's PSHE. Lots about for example friendship issues and resolving conflict, online safety. Yet students still write nasty things online, exclude people etc...
School can only do so much - essentially it's up to the individual to make their own choice in life.
I don't think the OP is criticising those who split with a partner and end up single. It's more the fact that women knowingly have children with someone who isn't ever going to be a good parent.
A lot of children in single parent households are on pupil premium. So it does cost the taxpayers money. I am personally happy to support children in this situation as it's not their fault. Unfortunately those children are highlighted in school as being pupil premium, graphs on their progress, discussed at meetings. We no longer have photos up on staff room wall but it's on provision map, class charts. Ofsted use as a criteria under disadvantaged. Obviously the aim is to level up and decrease the gap. But to have a child knowing that they will be always at a disadvantage from the start isn't great. I stopped at 2 because I didn't have the money for more.
I think there are also women who ignore the fact that their partner isn't keen & assume he will step up once the child arrives. Then he never does & they post on Mumsnet moaning about their useless DH.
