So many people who struggle to understand how societies are maintained.
"I have a private pension and my own money, and I pay more for other people's children!"
Your pension is worth 0. Nothing, unless there is a young generation to keep the country and the economy running when you are old. Without that, whatever pot of cash you have will be worth nothing after an economic or worse societal collapse.
There seems to be this idea that birthrates don't impact society.. and therefore it can go down, and the economy will be fine.. it can go down and climate change will be better.. nothing bad will happen. Because? Immigration? Except those countries also have falling or slowing birth rates... Because AI? That isn't exactly a dream scenario.
The reality is everyone, with or without children, needs the next generation. There are no exceptions, it doesn't matter how rich or idependant you are. You need a future capable generation.
That is why everyone pays for it.
Parents pay more, hugely more, because they choose to. Both financially and in labour. Those without children will enjoy the rewards of the stable society maintained by that labour. There is nothing wrong with that, there are plenty of other societal roles as well as raising children, and some people can't. Nothing wrong with it, except it does need to be acknowledged that parents make a huge contribution to the future of any nation.
In the case of Germany? Good, it sounds like they are a few steps ahead of the uk. We currently are facing a future of elderly care that we won't be able to fund. What are we going to do about it? Maybe not this, but over the next few decades there will need to be changes, and I wouldn't be surprised if they include children being forced to take on more responsibility for their parents. And for those without children, the state.
