There are other problems more closely related to the question of culture. The poor fit between large scale and Korea's familistic tendencies has probably been a net drag on efficiency. The culture has slowed the introduction of professional managers in situations where, in contrast to small-scale Chinese businesses, they are desperately needed. Further, the relatively low-trust character of Korean culture does not allow Korean chaebol to exploit the same economies of scale and scope in their network organization as do the Japanese keiretsu. That is, the chaebol resembles a traditional American conglomerate more than a keiretsu network: it is burdened with a headquarters staff and a centralized decision-making apparatus for the chaebol as a whole. In the early days of Korean industrialization, there may have been some economic rationale to horizontal expansion of the chaebol into unfamiliar lines of business, since this was a means of bringing modern management techniques to a traditional economy. But as the economy matured, the logic behind linking companies in unrelated businesses with no obvious synergies became increasingly questionable. The chaebol's scale may have given them certain advantages in raising capital and in cross-subsidizing businesses, but one would have to ask whether this represented a net advantage to the Korean economy once the agency and other costs of a centralized organization were deducted from the balance. (In any event, the bulk of chaebol financing has come from the government at administered interest rates.) Chaebol linkages may actually serve to hold back the more competitive member companies by embroiling them in the affairs of slow-growing partners. For example, of all the varied members of the Samsung conglomerate, only Samsung Electronics is a truly powerful global player. Yet that company has been caught up for several years in the group-wide management reorganization that began with the passing of the conglomerate's leadership from Samsung's founder to his son in the late 1980s.72 A different class of problems lies in the political and social realms. Wealth is considerably more concentrated in Korea than in Taiwan, and the tensions caused by disparities in wealth are evident in the uneasy history of Korean labor relations. While aggregate growth in the two countries has been similar over the past four decades, the average Taiwanese worker has a higher standard of living than his Korean counterpart. Government officials were not oblivious to the Taiwanese example, and beginning in about 1981 they began to reverse somewhat their previous emphasis on large-scale companies by reducing their subsidies and redirecting them to small- and medium-sized businesses. By this time, however, large corporations had become so entrenched in their market sectors that they became very difficult to dislodge. The culture itself, which might have preferred small family businesses if left to its own devices, had begun to change in subtle ways; as in Japan, a glamour now attached to working in the large business sector, guaranteed it a continuing inflow of Korea's best and brightest young people.73
