Almost every Disney movie involves a child rebelling against their parents.
The most Disney did before Eisner or, more accurately, Katzenberg took the wheel was promoting traditional American values if we are to go by propaganda. Beyond that, Walt generally avoided pushing for any propaganda, even of his own side (otherwise, the films would be blatant promotion of Barry Goldwater for example).
