I stopped sending money to United Way many years ago. They claimed that you could choose the organizations you DIDN’T WANT your money to go to, but they were lying because they allot a percentage to each organization they support before they even get the money. If you say you want your money to go to A, but not to B, B will still get the same percentage alloted to it beforehand.
Good info — I’ve always wondered if this wasn’t true even though one named their special charities.
