See - that's the thing. Lots of us can't commit to that because we're still securing the consistency of those resources for ourselves. All I'm saying is I don't agree with "I'm way too preoccupied" when I see the following grocery list as a very tall order for most people starting off today.
> Kids are sensitive to their social conditions but oblivious to their material situation until they've entered preadolescence.
As someone who grew up in a family with even mild struggles... yeah this just doesn't hold up. Lots of kids know as early as when they enter school. You notice the gaps between you and your peers almost immediately and often will have peers point it out to you because the poor kid is easy to pick on. You wear different clothes (second hand/etc), you probably struggle a bit with school, you don't have the cool video game system, you don't get to do the cool stuff other kids do... etc etc.
Kids notice way earlier than preadolescence.
I alluded to this in a different comment, but I think for most people the uncertainty is a bigger impediment than absolute conditions. If you had poor material conditions, but could at least count on them to remain stable no matter what, you could make that work as fair as raising a family. But the defining feature of the contemporary economy is that you'll never have that certainty: at any minute you might go from material security to being kicked out onto the street, and in the US at least you'll get no help except "Guess you shouldn't have had children lol; pull yourself up by your bootstraps loser."
> This can be pulled off even in times of great economic insecurity (think about all the depression-era babies).
I'm not sure what you mean by "all the depression-era babies". The Great Depression had the lowest birthrate the US had ever seen, and it did not pick up again until after the war: [0]

(Of course, the same comic also notes "They did it, therefore I'm here, therefore I can do it" is the mother of all confirmation biases ;) )
