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. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. Credit union services are available only to its shareholders. 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 relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations.
