Leeds Jewish Welfare Board president Edward Ziff has accused the community of not doing enough to support the charity.
Addressing some 80 people at the LJWB's 132nd annual meeting at the Marjorie and Arnold Ziff Community Centre on Monday evening, Mr Ziff said that fundraising is always a crucial issue.
"It is politically correct to say that the community is 'doing well' but the reality is that while this community is as affluent as it has ever been that does not show itself in the form of an outward support of this organisation."
The LJWB touches the lives of half the Jewish families in Leeds who use its services, he said, but still less than 25 per cent of Jewish households in the city contribute to its appeals.
