I feel like the comment about voting makes perfect sense? They’re saying that children don’t vote, but old people do, so of course it’s the latter group that gets the most resources - they vote, so they have power over politicians, so politicians cater to them.

That said, I think you have a good point with the rest of your comment.

Edit: Oh I think I see the confusion now. Did the grandparent change their comment? At any rate, my understanding is that they’re saying that for each dollar the government spends on a child, it’s spending three dollars on a person over 65.
