The Walters parents have issues with finances and yet couldn't even consider the fact that they had too many mouths to feed. They couldn't even consider Uncle Richard coming to the rescue with Jackie or getting lazy kids like Alex, the two cousins and anyone who is old enough to work to get casual or part time work to help out.
Cole was the only one working but had mental health issues and the parents didn't address them (like at the awards night). I watched the show thinking I am such a good parent to my two kids!
