Not RTFT and will probably get flamed for my responses but I completely agree and more, OP.
It shouldn't be the norm that babies are placed in nurseries full time sometimes from being under 1. No judgement for those that do by choice but it shouldn't be the norm through lack of choice. In many cases, by far the best thing for children under school age is to be home with a parent, just as it used to be. It also shouldn't be the norm that children as young as 4 are in preschool care from 7:30am then school then after-school care up to 6pm. It's my opinion that 4 is far too young for full time school anyway.
Modern society is a grim treadmill where families are routinely forced to have two working parents, too often doing jobs they see no real meaning in other than financial reward to keep their family afloat, and everyone is spread far too thinly. For too many families, it becomes a vicious cycle where there is no way out. The amount of times I've seen posters castigated on here for not working - we should be seeing families as households where if one adult is working, that should be adequate. Families should be able to survive with one working parent (or two part time perhaps) to enable the family to be prioritised.
Capitalism has broken communities. The supermarket decimated the corner shop and the suburban mini high street, where local people would shop and see each other regularly, and adult (yes, usually mum) was home with young children, building strong relationships and support networks with other mums. Roles were clear and delineated. I don't advocate for a return to a lack of choice for women - I would advocate for the ability for women (and men) to choose to return to a more traditional set up, no matter how this is structured in terms of gender. Now, you have to have an adult in the household earning a significant amount to be able to access a life where one adult can be at home raising children, being there at the start and end of the school day, maintaining the home so that weekends and evenings can be relaxed and free for family time and hobbies etc.
I believe that a different way of life is possible but in many cases, it means a different approach and in many cases, accepting sacrifice to standard of living by reducing spending, eating differently (more time for cheaper home-cooked meals if someone isn't working), forgoing expensive holidays and doing things more cheaply. It's a different topic really but home education (even if not for the full school age period) is also a wonderful option for those who feel their children have been shoved onto life's treadmill too early and would prefer a more home-based existence. I realise this isn't possible for everyone and that it's not the right choice for everyone either. Essentially, there should be room for choice - have two working parents and put the children into childcare from a young age or choose to have a parent at home with them or some combination of the two, whatever works best for your family, but families should be able to choose, especially during the 0-5 years but also beyond.
