The ethnic composition of the population - and the particular mixture of nationalities, languages and cultures - is a matter of importance to all nations. The selection of immigrants should not be seen primarily as a test of which nationalities are best. It is more important to select immigrants with an eye to the collective effect on the nation. An immigration policy is not a symbol, a banner, of a nation's attitude to other peoples or races; and to reject potential immigrants is in no way to doubt the worthiness of their nationality or culture.
