Both in the employments which the Fair Labor Standards Act covers and in the exemptions it makes, the Congress has cast upon the courts the duty of making distinctions that often are bound to be so nice as to appear arbitrary in relation to each other. A specific situation, like that presented in this case, presents a problem for construction which may with nearly equal reason be resolved one way rather than another. Except when a conflict between Courts of Appeals requires settlement by this Court, it does not seem to me very profitable to bring the individual cases here for adjudication. But since this case is here it has to be decided. The nature of the problem being what it is, I acquiesce in the judgment that commends itself to the majority of my brethren.
