For This Question,refer to the Following Passage

For this question,refer to the following passage. And is this not the whole drift of our society? We are not interchangeable in the sense of being people without differences,but in the externals of existence we are united by a culture increasingly national.And this is part of the momentum of mobility.The more people move about,the more similar American environments become,and the more similar they become,the easier it is to move about.
More and more,the young couples who move do so only physically.With each transfer the décor,the architecture,the faces,and the names may change;the people,the conversation,and the values do not-and sometimes the décor and architecture don't either....
Suburban residents like to maintain that their suburbia not only looks classless but is classless.That is,they are apt to add on second thought,there are no extremes,and if the place isn't exactly without class,it is at least a one-class society...."We are all," they say,"in the same boat."
William H.Whyte,Jr. ,The Organization Man,1956
