It's true that families don't look or act exactly the way they did when you or your grandparents grew up. But they do just about the same things they always did. They feed and shelter, care for one another, and socialize their young. And as things change, they change. But that doesn't mean that kids aren't getting fed.

Most teens expect to get married and raise children. Most divorced people get remarried within a few years. Time and again, Canadians tell pollsters that our families mean more to us than almost anything else. So maybe the problem isn't with families or selfish people. Maybe it has more to do with the hurdles we make families jump over.
