I never heard of a single one of the “charities” on their list.
Granted, some of the names on the list sound very much like well-known charities, which I assume are mostly on the level.
The left side-bar on the list explains that the most reputable charities pass on more than 36% of their proceeds.
36%!
Did you ever read Lenny Bruce’s autobiography? He describes his own scam in Miami. He went door to door wearing a cleric’s collar collecting for some charity— I think it was orphans or something. The cops tried to nail him but they couldn’t; all he had to do was write a check for 1/3 of the proceeds to some recognized party. He kept the rest.
It’s an excellent business to be in these days. If you want to want to expedite things with the IRS you should append the words “Progressive”, or “Alliance” to the front of your charities name.
