Jeff Greenfield said this quote

It was more than just material prosperity. America in 1960 was a country where restraint and boundaries were the natural conditions in all arenas. People married younger and stayed married; even with those added twenty-eight million, there were fewer divorces in 1960 than there had been a decade earlier. People did not have children unless they were married—only 2.5 percent of children were born out of wedlock, though the number in black households was disturbingly high—some 20 percent.
