Our experience, as we talk to charities across the country, is that as the charitable tax credit goes up, people see they have more room in their disposable income to give, they're passionate about what they're going to give to, and they will.
There is maybe a question of leakage. If you go from 29% to 42% for every $1,000, there's $130 there that it's costing the government. Some may say, “Yes, there's some leakage. We'll keep $70 of it and give away the difference.”
I'd take the risk on that issue. I just don't see any other alternative that accomplishes your interest as well.
