These concepts are evidenced by the fairly egalitarian nature of American families and marriages.
In American marriages and families today, there is much less "authoritarianism" than there once was. In marriages, we no longer see the kind of "husband is boss" ideas that we once did. Marriages are much more equal, with both partners sharing responsibilities for earning money, caring for children, etc. American families are also relatively egalitarian. When compared with some other cultures, we do give our children much more of a voice in family affairs and we are much more willing to see our children as people who have opinions and feelings that need to be respected. These are attitudes that seem to be influenced by the fact that our society emphasizes freedom and democracy.
