I guess its more convenient not too, and enough people are selfish enough and stupid enough to buy the idea that no one should receive any financial support, yet those same people are more than happy to accept final support themselves in the NHS, free university, state pension, family allowance etc.
Where we now live things are more children and family centred, for us a month of fulltime childcare here would cost less than what we were paying for one day of nursery in the UK. Here all children from 12 months are entitled to a fulltime pre-school place. Just like a child over 5 in the UK is entitled to a primary school place. For us this costs about £89 a month, if our daughter was our first child it would be about £140 a month. I think the funding for childcare here is about 1.9% GDP.
Wrap around is available at primary school age, however its also common that once children hit compulsory school age they walk to and from school, our eight year old does. So working isn’t as awkward. However employers are far more flexible, its completely normal for employees to have flexible working, no matter their home situation. Holidays are also treated differently, its common for work places to shut down for the entire summer, or to rely on teens and young adults to be seasonal workers so others can have the whole summer as holiday.
The birth rate however is still low, if you don’t want children no amount of cheap childcare will persuade you to have children. Having children will always be a sacrifice as you sacrifice time, sleep, money, space etc.
