That's kind of harsh, it's not necessarily the Mom's fault. As they say, you can lead a horse to water but you can't make it drink. I know plenty of adult landwhales that were brought up in shitlord families. They were taught how to eat healthily, how to cook properly nutritious food and how to generally take care of themselves. They then moved out on their own and expanded faster than the universe in the first milliseconds of the big bang. If a person is lazy, all the good parenting in the world won't help them once they're no longer living at home with all the "hard work" of shopping and cooking proper food done for them!
