School is not childcare, correct.
Childcare where I live is scarce, with long waiting list.
Depending on the area, childcare can be very expensive, not that is not something valuable, or doesn't worth the price, but about 1000 pounds a month is a big chunk of money that not everyone have.
Affordable alternatives to the core working class parent are little, and we do as much as we can, reducing hours, WFH, getting more flexibility etc.
School was 9 to 5 when I was a kid, where I am from and here I am with no more traumas that most of the people I know, in fact I fondly remember my teachers and my class mates. A few of them are still good friends, this was more than 40 years ago.
Nurseries are mostly funded in other countries and come to a maximum cost of half of what we pay here. A third of the cost in most cases.
Alternatives exist and work in other places, the fact that here is different doesn't mean the rest got it wrong, is just different.
It is like the uni degrees, you pay for them in England and you don't need too or at least you don't have to pay that grueling sum in Scotland. I know professionals from both places and I can't see much difference other that the English got in more debt.
For those who thing that we should have to think about this before having kids, well, circumstances changes and, losing a job, sickness, divorce, childcare closing down, family that provides childcare no longer be able to do it for a reason or another and death happens all the time. We can't sort that out before happening? No one can, no even those who think the have done.
Call it school, call it wraparound and early breakfast, there should be more available.
