The advantage of national planning is its ability to remove the wastes of oligopolistic anarchy, i.e. meaningless product differentiation and an imbalance between different industries within a geographical area. It concentrates all levels of decision making in one locale and thus provide each region with a full complement of skills and occupations. This opens up new horizons of local development by making possible the social and political control of economic decision-making. Multinational corporations, in contrast, weaken political control because they span many countries and can escape national regulation.
