Classicly

American life, in this year 1925, consists essentially of surfaces. You may point out New England communities and say here is depth, and I will answer, true, but New England is dead so far as the America of now is concerned. 

I have used a Jewish youth as my protagonist because the Jews are determining the nature and scope of jazz more than any other race—more than the negroes, from whom they have stolen jazz and given it a new color and meaning. Jazz is Irving Berlin, Al Jolson, George Gershwin, Sophie Tucker. These are Jews with their roots in the synagogue. And these are expressing in evangelical terms the nature of our chaos today.
