Does Tocqueville believe that “self-interest well understood” (DA, pp. 500-506) is sufficient to combat individualism and materialism?

While Americans generally do not speak of the abstract beauty of virtue, they recognize its usefulness and realize that "by serving his fellows man serves himself and that doing good is to his private advantage." While the doctrine of self-interest properly understood does not lead to great virtue, it does establish virtuous habits. Because this doctrine is not always entirely self-evident, it is necessary to educate people about it.
