Blame It All on the '70s?

If the left and right agree on almost nothing else, we agree at least on this: America's in terrible shape. Such shocking shape that -- how did we come to this? -- it might not actually survive.

And there our dialogue dissolves. The things about America you diagnose as lethal are the very things your megachurch-belonging cousin with the rifle rack in his truck prays might save its life. And vice-versa. Gay rights. Abortion rights. Prayer in the schools. Environmentalism. Corporations. Porn. There the shouting, and possibly shooting, begins.

How did we come to this? It's the '70s' fault, writes Thomas Hine in The Great Funk: Falling Apart and Coming Together (on a Shag Rug) in the Seventies (Farrar Straus Giroux, 2007), a richly if incriminatingly illustrated book about a traumatic "slum of a decade" in which "the country was running out of promise."

Well, the '60s were a hard act to follow.

"Only a decade before," Hine muses, "as the nation anticipated the conquest of space, the defeat of poverty, an end to racism and a society where people moved faster and felt better than they ever had before, it seemed that there was nothing America couldn't do." Flash-forward through Watergate, gas crises, helicopters escaping Saigon -- and "to live in the seventies was to live in a fallen world, one of promises broken and trust betrayed." Hine ticks off that decade's insults to heart, mind and eye: "The politicians were awful. The economy was awful. The insipid harvest gold and avocado kitchens were awful." Ditto gas lines, AMC Pacers, and pantsuits.

Nearly everyone who lived through those years would nod, flinching.

An eternal question about any era during which one was young is: Was the whole world embarrassing, or was it just me? As regards the '70s: It wasn't just you. A longtime design critic -- thus more sensitive than most to beanbag chairs and Bicentennial-patterned carpeting -- Hine painstakingly skewers pyramid power and Virginia Slims in chapters whose pop-culture-referencing titles evoke the chronic inferiority complex of those disappointed times: "Running on Empty," for instance, and "It's Too Late," and "Not Ready for Prime Time?"

Yet his skewering has an obligatory quality, a must-mock-Midler delliberateness. It's a setup. Because this book's real point is to burrow deep into the shag rugs and chest hair and extract wisdom. Yes, your dad lost his job. And disco sucked. But from an era that is all too easy to dismiss as silly, trivial and grim sprang most of the essential issues inflaming our discourse today. Grounds for celebration or destruction or for civil war, depending on whom you ask, were cultivated in that decade, in a petrie dish that smelled of Diet Pepsi, amyl nitrate, apple-spice air freshener and, well, funk.

Ecology. Diversity. Ethnic and sexual identity. Individuality. Alternative sources of energy. Feminism. Fundamentalist spirituality. Retrace our steps (in Earth shoes and a crocheted vest and Dacron flares, of course) through Jimmy Swaggart and solar-heated geodesic domes and blaxploitation films and the Village People and you will find it there, albeit all innocent and earnest and embryonic. And not just the topics themselves but the ways in which we face them now: our wary citizen-journalist vigilance, questioning authority, scoping out conspiracies, pursuing truthiness. The '60s tend to get all the credit -- for rebellion, for consciousness-raising, for everything. And those who were young in the '70s faced a deafening chorus roaring: You missed the boat and are, indeed, too late.

The era they'd missed had been imbued with a wild easy-rider-come-together optimism. "Even the protestors of the sixties," notes Hine, who is old enough to have been one of them, "objected that America was using its immense wealth and power to do the wrong things, not that it did things wrong. Yet during the seventies it seemed that the United States couldn't do anything right." And it was precisely that shattering of optimism, the serial humiliations of Nixon and Vietnam and ugly urban sprawl and the wracking poverty spawned by inflation and massive layoffs, that spawned a strange new kind of solidarity. A desperate bottom-of-the-barrel creativity. The sneaky kind of freedom that breaks chains and opens doors when -- to paraphrase Kris Kristofferson's "Me and Bobby McGee" -- you've got nothing to lose. And that, of course, was the last song Janis Joplin recorded before she died in 1970. Among baby boomers, Hine writes, "the song's refrain ... was heard as a kind of epitaph." Her death was itself a loss, thus one less thing to lose. As was Jimi's, one month before, and Jim Morrison's, one year hence. As was the Beatles' slow-motion collapse: mere markings on a timeline now and, to most, funny ancient history: Yoko smiling and smug, Linda singing off-key into a switched-off mic, flashing past in the neat anodyne black-and-white of documentaries. But to a generation raised to be the center of attention, the first wave to worship rock-'n'-roll, these losses wrought a shocking loss of innocence. The long and winding road was cracked.
