I honestly think that the sorts of experiences that break kids are things like parents breaking up, not 'not having the newest toy' or 'not going on vacation'. In the sense that material poverty can cause family stress, I completely agree. I fully support programs to feed kids, provide medical insurance, etc. I even support it for adults. I'm just not sure how any of that at the end of the day is going to fix daddy cheating. Unless you're suggesting a crackdown on prostitution and/or making adultery a crime again (in which case sure! as a social conservative, I'm down)... but good luck getting that passed today!
Another point is that if you're not thriving as an adult, it could be because of the experiences you had when you were a kid.
