Two-Layer System
Personality is to a large extent inherent. A-type parents usually bring about A-type 31 . But the environment must also have a 32 effect, since if competition is important to the parents, it is likely to become a major factor in the lives of their children.
One place where children soak up A-characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools 33 the" win at all costs" moral standard and measure their success by sporting   34. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A-types seem in some way better than their B-type fellows. Being too 35 to win can have dangerous consequences : remember that Pheidippides, the first marathon runner, dropped dead seconds after saying :"Rejoice, we conquer !"
By far the worst form of 36 in schools is the disproportionate emphasis on examinations. The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of 37 is positively harmful.
Obviously, it is neither practical nor 38 that all A youngsters change into B' s. The world needs types, and schools have an important duty to try to fit a child' s personality to his possible future employment. It is top management.
If the preoccupation of schools with 39 work was lessened, more time might be spent teaching children surer values. Perhaps selection for the caring professions, especially medicine, could be made less by good grades in chemistry and more by such considerations as sensitivity and sympathy.It is surely a mistake to choose our doctors 40 from A-type stock. B's are important and should be encouraged.
