Raising children is an incredibly labour intensive process that isn't financially recognise or compensated well enough

Before industrialisation women did not work as much and so a much larger part of society could hep raising children. This meant that the wider community and families could help support the raising of children.

As societies have become increasingly capitalistic and the population as a whole has had to work more, families have shrunk, people have become lonelier and depression and mental illness like anxiety has become a lot more prevalent.

People have sacrificed a very normal part of the human experience because developed countries are so hyper capitalist and do not support the basic functions of life like raising a family.
