In Bangladesh, however, it seems that this approach is not adequate. Frequently, the defaulters are the larger, powerful farmers who are immune to village social pressures and may, in fact, have a vested interest in the collapse of institutional credit, which might compete with their own money-lending activities. In such cases, it would seem that the application of police and judicial power, involving the seizing of mortgaged properties, is necessary to supplement social pressures. Alternatively, different groups might be set up of small, medium, or large farmers, so that members have roughly equal status. In general, Adams reports that groups established for the sole purpose of obtaining credit lack viability. For landless laborers, group activities in the form of labor unions can be extremely useful in improving not only wage levels but also working conditions (including stability of employment, dignity of treatment, etc.) This has been amply demonstrated in Kerela, India, among other places. In some cases local groups will form spontaneously, as expansions of previously existing voluntary organizations. This is most likely to happen where land ownership is reasonably egalitarian and where government is tolerant of local organization. The Grange movement in the U.S. and the cooperative movement in Denmark are two examples. In most cases, however, active government support for all these forms of group activities is needed. Careful, thorough supervision and checking from higher levels and the effective utilization of police and judicial power seem necessary to nip in the bud the first indications of corruption. Training programs are also useful to assure competence in organizational management as well as technology (e.g., bookkeeping, etc.). Government regulations that require groups to be composed of homogeneous farmers (i.e., all small, medium, or large) can be helpful in preventing patron-client relationships
