This is incredibly true, and has been a growing problem from before LLMs came around. Even wealthy families who presumably have plenty of resources they could use to better their children's fates are failing their kids. My sister is a teacher in a well-off school district and has to buy food out of her own pocket (on a teacher's salary) to give to her students because so many haven't even had anything to eat before they show up.

I mean, these are bare minimum things, people.
