Walk through a catalog of Disney films. I don't care how far back you go and see how many of them actually feature an intact family, i.e., a mom, dad, and children. There really aren't very many. Lots of aunts, uncles, single moms and dads, etc. (though most of the time the single parent is widowed.
Many of the older movies are based on fairy tales which are notoriously hostile toward parents in general. (birth mother dies, beta male father marries an evil step-mother, etc.)
