I'm childless, I will very likely be childless my whole life but this attitude is both: very naive, very ignorant and very very reductionist.
I'm happy that my taxes here in Sweden pay for child support, childcare and schools that I won't ever use, because that is the basic fabric of this society.
Also, it's very rare that people think they are going to bear a child to improve society. Adoption would make much much more sense if that was their goal.
In any case, people want to have children, sure.
Then they complain that having a child is so tough so much hardship (e.g. no vacation ever in this thread, child tax credit is not enough). Then, they turn to society to support them in an unfair way
Almost everyone knows the estimated cost and effort upfront. There are tons of materials and prior experience.
It's like me spending all my cash on Tesla and then complain that society doesnt support me enough.
Yes it is a decision. Sometimes selfish, most often foolish, but in all cases needed. And all benefit.
It's so strange to complain that government doesn't cover the cost of your child. You choose to have your child. I'm sure you plan to support your child.
This is like me complaining that government doesn't subsidize my Tesla.
