I think there may be two things to assist you in this kind of consideration.
Number one is the investigation of existing research to actually illustrate that a tax strategy is the best tool to attract new donors into the charitable world. At Cardus, we don't know of any solid or substantive research that actually makes that argument, that proves it.
We know by experience that the charitable tax credit itself prompts donations. That's not in question. So I think the first piece would be to look for research, if it's out there. We have not been able to find the research that proves the ability of a tax measure to attract new donors. It's our sense that this is a cultural issue. To attract new donors is more of a cultural issue than it is a tax strategy.
The second is a question about whether it's material to the whole charitable sector. On the stretch credit, the challenge with it—and remember, if you just increase the charitable tax credit itself, you accomplish the interest of the stretch credit as well—my sense is that the dollar amount the stretch credit will raise is not going to be significant to the challenge that the charitable sector is actually dealing with.
In a way, by acknowledging the stretch credit, we're saying “here's the solution”, but it's a solution to a very small part of the problem. We already know that tax measures are only one small piece of the solution. Why would we employ a tax measure like the stretch credit that just simply is not material enough to capture the enormity of the challenge we're dealing with?
