I know it's just an anonymous rant but really, not a good way to view the world or your child.
Sacrifice to gain control via indebtedness - underhand manipulative ness and an abuse of power.
My mother lived that horrible way of thinking, and like others, it's left me damaged and without a parental relationship. Perhaps that's the problem with this article - the writer may just be venting, trying out this mode of thinking for exaggeration and for rant purposes only, but unfortunately people really do behave like this as a way of life, not just in an article!
Making sacrifices that someone hasn't asked you to, that they weren't in a position to even understand or consent to... and then presenting them with the bill, a maxed out credit card that the child didn't even know had been taken out in his/her name, that they can only pay off with subservient submission, or constant thankfulness... Not a parenting technique I admire, to put it mildly.
