70 We would also say a word to those who travel to newly industrialized nations for business purposes: industrialists, merchants, managers and representatives of large business concerns. It often happens that in their own land they do not lack a social sense. Why is it, then, that they give in to baser motives of self-interest when they set out to do business in the developing countries? Their more favored position should rather spur them on to be initiators of social progress and human betterment in these lands. Their organizational experience should help them to figure out ways to make intelligent use of the labor of the indigenous population, to develop skilled workers, to train engineers and other management men, to foster these people's initiative and prepare them for offices of ever greater responsibility. In this way they will prepare these people to take over the burden of management in the near future. In the meantime, justice must prevail in dealings between superiors and their subordinates. Legitimate contracts should govern these employment relations, spelling out the duties involved. And no one, whatever his status may be, should be unjustly subjected to the arbitrary whim of another.
