Adapted from Brink Lindsey's The Age of Abundance:

On April 5, 1967, representatives of the San Francisco Oracle, the Diggers, the Family Dog, the Straight Theater, and other parts of the Haight-Ashbury hippie scene held a press conference to announce the formation of the Council for a Summer of Love. The event scored friendly media notices: The next day's San Francisco Chronicle described the coalition as "a group of the good hippies," defined as the ones who "wear quaint and enchanting costumes, hold peaceful rock 'n' roll concerts, and draw pretty pictures (legally) on the sidewalk, their eyes aglow all the time with the poetry of love."

Three days earlier and 1,500 miles away, in Tulsa, Oklahoma, a very different counterculture was holding its own coming-out party. About 18,000 people--far more than the 4,000 anticipated--gathered for the formal dedication ceremonies at Oral Roberts University. Oklahoma's governor, a U.S. senator, two members of Congress, and Tulsa's mayor were on hand. Delivering the dedication address, "Why I Believe in Christian Education," was Billy Graham, the dean of American evangelists.

The events in San Francisco and Tulsa that spring revealed an America in the throes of cultural and spiritual upheaval. The postwar liberal consensus had shattered. Vying to take its place were two sides of an enormous false dichotomy, both animated by outbursts of spiritual energy. Those two eruptions of millenarian enthusiasm, the hippies and the evangelical revival, would inspire a left/right division that persists to this day.

That split pits one set of half-truths against another. On the left gathered those who were most alive to the new possibilities created by the unprecedented mass affluence of the postwar years but at the same time were hostile to the social institutions--namely, the market and the middle-class work ethic--that created those possibilities. On the right rallied those who staunchly supported the institutions that created prosperity but who shrank from the social dynamism they were unleashing. One side denounced capitalism but gobbled its fruits; the other cursed the fruits while defending the system that bore them. Both causes were quixotic, and consequently neither fully realized its ambitions. But out of their messy dialectic, the logic of abundance would eventually fashion, if not a reworked consensus, then at least a new modus vivendi.
