Yes, that&#x27;s why Australia and Canada are such disasters.   In both of those countries immigrants, the children of immigrants and the grand-children of immigrants form the vast majority of the population of the country.<p>And in those countries, experience shows that the grand-children of immigrants have far more similar values, desires, opinions and habits as their peers than they do to contemporaries in the original home of their grandparents.<p>The average black family in the United States has been in the United States for <i>longer</i> than the average white family.  That blacks and whites in the United States are not essentially homogeneous even though they mostly went to the same schools, participated in the same economy, spoke the same language and experienced the same media is purely an artifact of deliberate exclusion.
