Alba writes (p. 7) that “the changes involved in assimilation can be more radical than most Americans now appreciate, for assimilation ultimately affects the way that group differences ae perceived. This sort of assimilation has had an especially strong impact on some once-denigrated European groups, such as Irish Catholics and those from southern and eastern Europe. In order to appreciate the magnitude of assimilatory change, which has caused the distinctions based on different European origins to fade to the point of near invisibility in much of social life, it is important to recognize how our ‘eyes,’ our perceptions, have been altered as a consequence.” Explain what Alba means by this? Could distinctions between Asian-American and Americans of European background similarly fade to the point of near invisibility? Justify your answer.
