Found this at Sam Weller’s bookstore in Salt Lake City. It looks to be good. The synopsis reads:
"If we were once a melting pot,” writes Peter Wyden, “we are no longer. The ingredients in the pot are separating and congealing . . . More and more kids come to know only their neatly manicured, fumeless, comfortably monotonous bedroom communities where there are almost no old people, no poor, no childless, no Negroes, either no Jewish families or many, no sidewalks, no places to explore except by mother-chauffeured car, no houses or incomes too different from those of their parents.“
And the best part: This book was published in 1962.
