The so-called Family Income Benefit introduced, or reintroduced, into this country some four years ago has received an astonishing welcome from the public. Its rapid popularity as an addition to the ordinary whole life or endowment assurance policies has a parallel only in the disablement income benefit granted by the American and Canadian Offices in North America. Although there is no reason to anticipate that the history of this supplementary benefit will follow the unfortunate course of the disablement benefit in America, an early examination of the problems connected with it is most desirable, for the policies are not without their pitfalls and limitations.
