Technically there is no such thing as an “American lawyer”: every state
admits its own, and a lawyer licensed to practice in Florida is strictly speaking
a layperson as far as Alabama or Alaska is concerned. Nonetheless, in the aggregate,
this is a vast army of lawtrained men and women.
The profession is, and always has been, quite diverse. There are many legal
worlds. To begin with, there is the world of the big firm. These big firms recruit
their lawyers, by and large, from the “national” law schools – with big
reputations and long traditions, like Harvard and Yale. We know in general
what the work is: it includes securities law, antitrust law, bond issues, mergers,
tax work, international trade. In both big and little firms, up to half the
work could be described as “litigation”.
Another staple of law practice is real estate: buying and selling houses or
concluding elaborate deals for shopping centers, suburban developments, and
office buildings, or converting luxury apartments into condominiums. Estate
work is also common to big firms and little firms alike. Big firms handle these
affairs for captains of industry and for great old families. Middle-sized do the
same for the medium-rich – manufacturers of plastic novelties, owners of restaurants,
car-wash companies, apartment buildings. Small-town lawyers and
solo practitioners handle farm estates. And so on.
Some branches of practice do tend toward specialization. There are lawyers
who work on port trade, on chartering ships, on show business (“entertainment
law”), on trademarks and copyrights. However, few lawyers are totally specialized.

Big-firm lawyers cover many fields and many problems. But there are areas
they definitely do not touch. One is divorce. It is the lawyers in smallish
firms and in law clinics, and the solos, who handle “one-shot” clients – couples who want a divorce, victims of car crashes, people arrested for drunk
driving. Some lawyers with one-shot clients struggle to make ends meet; others
earn heaps of money.
Since the early nineteenth century, law has been a prominent way “to get
ahead” in the society. For much of American history, a lawyer meant “white
male.” Black lawyers were rare birds in American history. Not a single
woman was admitted to the bar before the 1870s. Indeed, when women tried
to break into this all-male club, they met resistance and reluctance, to say the
least. Opinions changed, but slowly and grudgingly. Equality of opportunity is
not an easy goal to achieve, especially with regard to barriers of class. The
cost of legal education is one of these barriers. Lawyers tend to come from the
families of businessmen, teachers, professionals; they are not sons of grocery
clerks or coal miners’ daughters. Over 73 percent of the practicing lawyers in
Chicago came from “solidly middle-class or upper-middle-class-homes,” far
more than if lawyers were selected from Chicago families at random. Many
came from lawyerly or professional backgrounds not from working-class
backgrounds.
There are law schools in every major city and in almost every state, Alaska
is one of the few that lacks this modern amenity. These law schools are both
different from each other and much the same. They are remarkably similar in
curriculum and method. They also tend to impose the same general requirements:
a college degree, and the Law School Admission Test (LSAT). But law
schools are quite different in prestige, money and power – and in quality of
faculty and students. The stronger older schools are able to “skim off the
cream”. Harvard, Yale, Berkley, and Chicago can afford huge research libraries;
small schools cannot.
Lawyers, like Americans in general, are joiners. They are united into a
strong, permanent organization – the American Bar Association, the ABA, in
short. There are also state, county, and city bar associations. But the ABA is
still not an association of all American lawyers. No one has to join it though it
has a huge membership.
Law and lawyers are expensive. Many people who want or need a lawyer
have trouble paying the price. But the state provides a lawyer, free of charge
“public defenders”, to anyone accused of a serious crime who cannot afford to
pay on his own. For civil cases, the situation is more complicated. A few lawyers
have always made it a practice to do some work free for poor clients.
There are now a number of law firms organized for the “public interest”.
