Your experience resonates with me and I hadn't seen it into words until now. It's a fate that still drives me to work harder so my future kids wouldn't ever go through it. I read that some investors have a word for it "PSD": grown up Poor, very Smart and Driven.

I agree that the article talks about more well-off families since kids whining is mostly a tactic to get what they want. If the tactic never works it wouldn't be employed.
