what do childfree/childless people get instead of "parental leave?"

[Squinch]

562. If more people chose not to have children we would all be much better off.

Overpopulation is a major source of the climate change that is threatening us all. Our world is overcrowded and our resources are stretched to the breaking point.

That being said, once those children are born, I do feel that I - a childless person - have a social responsibility to help ensure they are raised to be productive and healthy.

However, my support is for the children, not the parents who chose to have the children.

The parents did CHOOSE. Presumably they knew they would be making those sacrifices you speak of, they weighed those sacrifices against the benefits they thought would be getting by having children, and decided that the benefits outweighed the sacrifices. So no one owes you anything because you decided you would be better off having children than not.

I do wholeheartedly agree that we need to make sure the children in our society are cared for, and I devote my professional life to that effort but I certainly don't think I owe you anything for having given birth to those children. No one needs to repay you for anything.
