To date, credit unions - virtually the only form of financial institution where people can quickly and without any problems get a relatively inexpensive cash loan. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity.
