It's amusing how that whole thing works where a child is forced into existence with no input on the matter whatsoever, yet the parents are shocked when that child requires time, money, and effort to raise. These are the parents who will tell their kids that their Christmas gift is "being allowed to live under my roof and eat my food." Umm no, that's not a gift, that's the bare minimum expectation for the child YOU created.
Of course children use their parents' resources - they don't have their own resources! It's astounding that grown men and women are surprised when they learn that kids require WORK and need caring for. I think some people honestly believe that when they have a kid, they just have to look at it once a week like a houseplant and it's somehow self-supporting in the meantime.
And I'm sure it's a real joy to grow up with parents like this who are keeping score as far as what they are "owed" for the kid's whole life. They are the ones who will say shit like, "...and after EVERYTHING I've done for you!" when the kid does something they don't like. As if food, clothing and shelther is a guarantee of good behavior.
