The falling apart or destruction of ethnic culture may result from cultural invasion, compulsory education, and other national policies which do not take ethnic considerations into account.
Ethnic disintegration is particularly marked among primitive tribes, but can also be seen among sects and ideological communities in industrialized countries (such as Jewish Americans) with their increasing nationalism and uniform national social policies.
We can assert with some confidence that our period is one of decline; and that the standards of culture are lower than they were fifty years ago; and that the evidences of this decline are visible in every department of human activities (T. S. Eliot).
