That's true. My argument is that before, when people had more children, they didn't care about bringing them into a bad world. Even 100 years ago it was expected some of your children will die.

Now, children dying is not a nice thing. Luckily we solved it and these days if you behave like our ancestors you will have too many children for society to be sustainable.

But if you're in a situation where there are too few children for a sustainable society, encouraging risk would help.

All being said, I actually believe we need to reduce the human population. But we don't know how to handle a sudden decline, or if we can level it out later. So a gradual decrease would be preferable.
