Interesting article in Haaretz about declining levels of contribution, among younger Jews, to mainstream Jewish organizations.
The positive news is that donations are still going to other, smaller charities and therefore overall donations to the Jewish community are up. However, the structure of giving right now is centralized, and many organizations require the central organizations to keep funneling funds to them in order to survive.
It should be noted that some leaders of the Jewish community are already clamoring to keep more of the donations in the U.S and Canada, instead of continuing to send 50% of the annual total to Israel. This is a no-brainer, and needs to be implemented asap. For more on why, please see comment, #13 and view the link in there.
