John Dewey (quote below) on how humans maintain our culture. We now have many sub groups in the US, good and bad, and they are maintained through everyday education. NOT school education, which as Dewey says, forms only a small part of what we learn in order to maintain our communities. It's clear a group cannot exist without new-born members being initiated. When a leader such as the president of the country reinforce the interests of a group, it helps maintain the group.
"there
is the contrast between the immaturity of the new-born members of the
group -- its future sole representatives -- and the maturity of the
adult members who possess the knowledge and customs of the group.
On the other hand, there is the
necessity that these immature members be not merely physically
preserved in adequate numbers, but that they be
initiated into the interests, purposes, information, skill, and
practices of the mature members: otherwise the group will cease its
characteristic life." John Dewey
