In his Nov. 7 commentary, "What's So Special About Credit Unions?" Bill Issac blithely suggested credit unions are no longer needed as an alternative type of financial institution. He maintains that credit union members are more affluent than nonmembers, that credit unions don't provide any services that other financial institutions don't provide, and that they can no longer justify their exemption from federal income tax.
However, it stands to reason that credit union members have higher incomes than noncredit union members; by definition, they're employed when they join, whereas nonmembers include the unemployed. Clearly, the relevant comparison the author avoids is credit union-member household incomes to bank-customer household incomes. Nor does he comment on nonbank customer incomes.
