Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. In the UK, credit unions are a source of financing of people groups. This tool is not widely used.
