The peasantry have long since disappeared, the independent shopkeeper is being destroyed, the small business-man is diminishing in numbers. But at the same time modern industry is so complicated that it cannot get along without great numbers of managers, salesmen, engineers, chemists and technicians of all kinds, drawing fairly large salaries. And these in turn call into being a professional class of doctors, lawyers, teachers, artists, etc., etc. The tendency of advanced capitalism has therefore been to enlarge the middle class and not to wipe it out as it once seemed likely to do.
