Names like Stern (who married a Gimbel) and Mellon bring that warm glow which emanates from vast, inherited fortunes. With aids like the Social Register, the Blue Book and the Almanach de Gotha, they are generally quite easy to identify. The poor, alas, are also often conspicuous. It's all those in between who are harder to categorise. Now my fellow-columnist Katherine Shonfield, in her pamphlet for Comedia, suggests a taxonomy for the silent majority: prostitutes and mistresses; criminals; the sick and the dead; the drunk and disorderly; babies, children and teenagers; the retired, and the disabled. Anyone feel marginalised?
