Anybody who still thinks of Wall Street in these terms, however, is getting his ideas from the novels of Auchincloss or Marquand rather than from the new, fast-changing reality. Today, Wall Street has splintered, and a young man entering the business has a choice of a whole clutch of competing subcultural affiliations. In investment banking the old conservative WASP grouping still lingers on. There are still some old-line "white shoe" firms of which it is said "They'll have a black partner before they hire a few." Yet in the mutual fund field, a relatively new specialized segment of the financial industry, Greek, Jewish and Chinese names abound, and some star salesmen are black. Here the entire style of life, the implicit values of the group, are quite different. Mutual fund people are a separate tribe.

"Not everyone even wants to be a WASP any more," says a leading financial writer. Indeed, many young, aggressive Wall Streeters, even when they do happen to be WASP in origin, reject the classical Wall Street subcult and identify themselves instead with one or more of the pluralistic social groupings that now swarm and sometimes collide in the canyons of Lower Manhattan.

As specialization continues, as research extends into new fields and probes more deeply into old ones, as the economy continues to create new technologies and services, subcults will continue to multiply. Those social critics who inveigh against "mass society" in one breath and denounce "over-specialization" in the next are simply flapping their tongues. Specialization means a movement away from sameness.

Despite much loose talk about the need for "generalists," there is little evidence that the technology of tomorrow can be run without armies of highly trained specialists. We are rapidly changing the types of expertise needed. We are demanding more "multi-specialists" (men who know one field deeply, but who can cross over into another as well) rather than rigid, "mono-specialists." But we shall continue to need and breed ever more refined work specialties as the technical base of society increases in complexity For this reason alone, we must expect the variety and number of subcults in the society to increase.

Even if technology were to free millions of people from the need to work in the future, we would find the same push toward diversity operating among those who are left free to play. For we are already producing large numbers of "fun specialists." We are rapidly multiplying not merely types of work, but types of play as well.

The number of acceptable pastimes, hobbies, games, sports and entertainments is climbing rapidly, and the growth of a distinct subcult built around surfing, for example, demonstrates that, at least for some, a leisure-time commitment can also serve as the basis for an entire life style. The surfing subcult is a signpost pointing to the future.

"Surfing has already developed a kind of symbolism that gives it the character of a secret fraternity or a religious order," writes Remi Nadeau. "The identifying sign is a shark's tooth, St. Christopher medal, or Maltese cross hung loosely about one's neck ... For a long time, the most accepted form of transportation has been a wood-paneled Ford station wagon of ancient vintage." Surfers display sores and nodules on their knees and feet as proud proof of their involvement. Suntan is de rigeur. Hair is styled in a distinctive way. Members of the tribe spend endless hours debating the prowess of such in-group heroes as J. J. Moon, and his followers buy J. J. Moon T-shirts, surfboards, and fan club memberships.

Surfers are only one of many such play-based subcults. Among skydivers, for example, the name J. J. Moon is virtually unknown, and so are the peculiar rituals and fashions of the wave-cresters. Skydivers talk, instead, about the feat of Rod Pack, who not long ago jumped from an airplane without a parachute, was handed one by a companion in mid-air, put it on, opened it, and landed safely. Skydivers have their own little world, as do glider enthusiasts, scuba-divers, hot rodders, drag racers and motorcyclists. Each of these represents a leisurebased subcult organized around a technological device. As the new technology makes new sports possible, we can anticipate the formation of highly varied new play cults.

Leisure-time pursuits will become an increasingly important basis for differences between people, as the society itself shifts from a work orientation toward greater involvement in leisure. In the United States, since the turn of the century alone, the society's measurable commitment to work has plummeted by nearly a third. This is a massive redeployment of the society's time and energy. As this commitment declines further, we shall advance into an era of breathtaking fun specialism – much of it based on sophisticated technology.

We can anticipate the formation of subcults built around space activity, holography, mind-control, deep-sea diving, submarining, computer gaming and the like. We can even see on the horizon the creation of certain anti-social leisure cults – tightly organized groups of people who will disrupt the workings of society not for material gain, but for the sheer sport of "beating the system" – a development foreshadowed in such films as Duffy and The Thomas Crown Affair. Such groups may attempt to tamper with governmental or corporate computer programs, re-route mail, intercept and alter radio and television broadcasts, perform elaborately theatrical hoaxes, tinker with the stock market, corrupt the random samples upon which political or other polls are based, and even, perhaps, commit complexly plotted robberies and assassinations. Novelist Thomas Pynchon in The Crying of Lot 49 describes a fictional underground group who have organized their own private postal system and maintained it for generations. Science fiction writer Robert Sheckley has gone so far as to propose, in a terrifying short story called The Seventh Victim, the possibility that society might legalize murder among certain specified "players" who hunt one another and are, in turn, hunted. This ultimate game would permit those who are dangerously violent to work off their aggressions within a managed framework.

Bizarre as some of this may sound, it would be well not to rule out the seemingly improbable, for the realm of leisure, unlike that of work, is little constrained by practical considerations. Here imagination has free play, and the mind of man can conjure up incredible varieties of "fun." Given enough time, money and, for some of these, technical skill, the men of tomorrow will be capable of playing in ways never dreamed of before. They will play strange sexual games. They will play games with the mind. They will play games with society And in so doing, by choosing among the unimaginably broad options, they will form subcults and further set themselves off from one another.

Subcults are multiplying – the society is cracking – along age lines, too. We are becoming "age specialists" as well as work and play specialists There was a time when people were divided roughly into children, "young persons," and adults. It wasn't until the forties that the loosely defined term "young persons" began to be replaced by the more restrictive term "teenager," referring specifically to the years thirteen to nineteen. (In fact, the word was virtually unknown in England until after World War II.)

Today this crude, three-way division is clearly inadequate, and we are busy inventing far more specific categories. We now have a classification called "pre-teens" or "sub-teens" that sits perched between childhood and adolescence. We are also beginning to hear of "postteens" and, after that, "young marrieds." Each of these terms is a linguistic recognition of the fact that we can no longer usefully lump all "young persons" together. Increasingly deep cleavages separate one age group from another. So sharp are these differences that sociologist John Lofland of the University of Michigan predicts they will become the "conflict equivalent of southerner and northerner, capitalist and worker, immigrant and 'native stock,' suffragette and male, white and Negro."
